Commentary - Genesis 38:1-5

Bird's-eye view

Genesis 38 is one of those chapters that polite company tends to skip over. It is a sordid, grimy, and deeply embarrassing family story. And yet, it is plunked down right in the middle of the triumphant narrative of Joseph. This is not an accident. The Holy Spirit does not do things by accident. This chapter is a stark and necessary reminder that the line of the Messiah, the tribe of Judah, was not a collection of plaster saints. Far from it. This is the story of how God, in His inscrutable sovereignty, brings His glorious purposes to pass not just in spite of human sin, but often right through the middle of it. Judah, who will receive the scepter, begins his personal story here by descending, geographically and morally. He separates from his brothers, marries a Canaanite, and begins a family that is immediately marked by wickedness and death. This is not a promising start. But the gospel is for unpromising people. This chapter, in all its earthiness, is essential for understanding the nature of grace. God's promises are not dependent on the moral performance of the men who carry them.

The chapter opens with Judah's departure and his immediate compromise. He turns aside from the covenant family and yokes himself to the Canaanites, the very people Israel was called to be separate from. His choice of a wife is not incidental; it is a spiritual capitulation. The sons born from this union are a disaster. Er is wicked, so the Lord kills him. Onan is selfish and rebellious, so the Lord kills him too. Shelah, the third, is withheld by a faithless Judah. The whole situation is a tangled mess of sin, death, and covenant failure. But right in this mess, God is working. He is preparing the way for a woman named Tamar, who will prove more righteous than Judah, and through whom the line of Perez, an ancestor of Christ, will come. This is how our God works. He writes straight with crooked lines.

Outline

Context In Genesis

The placement of Genesis 38 is a masterful stroke of divine authorship. It interrupts the Joseph narrative right after he has been sold into slavery by his brothers, with Judah playing a key, if compromised, role (Gen 37:26-27). Just as we are following Joseph down to Egypt, the camera suddenly pans over to Judah. Why? To show us the contrast. Joseph is descending into slavery, but he will remain faithful. Judah is descending into moral compromise, demonstrating the profound unfaithfulness of the very line from which the King will come. This contrast serves to magnify the grace of God. The scepter was promised to Judah (Gen 49:10), not Joseph, and this chapter shows us that this was a promise of sheer grace, not a reward for merit. It reminds us that while Joseph is a remarkable type of Christ in his suffering and exaltation, the actual line of Christ comes through this broken, compromised family. The mess of Judah's life makes the need for a Savior all the more apparent.

1 Now it happened at that time that Judah went down from his brothers and turned aside to a certain Adullamite, whose name was Hirah.

The phrase "at that time" connects this story directly to the preceding events, the sale of Joseph. While his brother is being carried off in chains, Judah is taking a walk. He "went down from his brothers." This is more than a geographical note; it is a spiritual statement. He is descending. He is separating himself from the covenant community, the family through whom God's promises were to flow. When a believer separates himself from the fellowship of the saints, he is rarely heading in a good direction. And where does he go? He "turned aside" to an Adullamite. Adullam was a Canaanite town. Judah is not just taking a vacation; he is seeking companionship and alliance with the world, with the very people God had warned his family against. Hirah becomes his friend, his confidant, and as we see later, his partner in sin. This is the first step in a long series of compromises. It begins with a seemingly small decision to separate and associate with the wrong crowd.

2 And Judah saw there a daughter of a certain Canaanite whose name was Shua; and he took her and went in to her.

Judah's descent continues. Having made a friend in the world, he now finds a wife there. The text is blunt: "Judah saw... he took... and went in to her." This is the language of lust and impulse, not of careful, covenantal consideration. It echoes the sin of the sons of God in Genesis 6 who "saw" and "took" wives for themselves. It also echoes the sin of Shechem with Dinah. Judah is not asking for his father's blessing, as Jacob did. He is not seeking a wife from among his own people, as Abraham insisted for Isaac. He is acting entirely on his own, driven by his appetites. He marries a Canaanite woman, the daughter of a man named Shua. This is a direct violation of the covenantal principle of separation. The patriarchs understood that intermarriage with the Canaanites was not just a matter of cultural preference, but of spiritual survival. To marry a Canaanite was to invite their idolatry and immorality into the heart of the family. Judah, the future royal patriarch, throws this wisdom to the wind. He yokes himself to a daughter of the land, and the fruit of this union will be rotten.

3 So she conceived and bore a son, and he named him Er.

The first consequence of this unholy union is a son named Er. The Bible does not tell us the meaning of his name, but it sounds ominously similar to the Hebrew word for "evil" or "wicked." Whether this was intentional or not, it was certainly prophetic. As we learn in verse 7, "Er, Judah's firstborn, was wicked in the sight of the LORD, and the LORD put him to death." The first fruit of Judah's worldly alliance is a man so corrupt that God strikes him down directly. This is a stark lesson. When we sow to the flesh, we reap corruption (Gal 6:8). Judah went looking for life and companionship outside the covenant, and the first thing he got was a son destined for death. God's judgment falls swiftly on the fruit of this compromised marriage, demonstrating His holy displeasure with Judah's choices.

4 Then she conceived again and bore a son, and she named him Onan.

The second son is Onan. His name is likely related to a word for "vigor" or "strength," but it has come down to us as a synonym for wickedness. Onan will prove to be just as rebellious as his older brother, though his sin is of a different sort. He is a man who lives for his own pleasure and selfishly refuses his duty to his brother's name. The pattern is clear: this is a dysfunctional and ungodly family from the start. Two sons are born, and both are wicked men whom the Lord will have to remove. Judah's attempt to build a family apart from God's people and principles is an unmitigated disaster. He is getting sons, but they are not sons of the covenant. They are sons of Canaan, and they bring death with them.

5 And she bore still another son, and she named him Shelah; and it was at Chezib that she bore him.

A third son is born, Shelah. The location is mentioned: Chezib, which means "deceitful" or "disappointing." This place name hangs over the birth of the third son like a dark cloud. And indeed, Shelah's life will be characterized by disappointment. He is the son Judah will faithlessly withhold from Tamar, perpetuating the injustice in his family. He is the son who should have carried on the family line, but he will be passed over. The whole enterprise is marked by failure and deceit. Judah went down, made a worldly friend, took a worldly wife, and had three sons who were, in order, wicked, rebellious, and a disappointment. This is the man God chose to be the ancestor of King David, and of the King of Kings. If this story teaches us anything, it is that salvation is of the Lord, and His grace is greater than all our sin.

Application

The story of Judah's descent is a cautionary tale for every believer. It begins with a small step away from fellowship, he "went down from his brothers." This is where so many spiritual disasters begin. We isolate ourselves from the church, from accountability, from the means of grace. Once isolated, we are far more vulnerable to the temptations of the world. Judah's friendship with Hirah quickly led to marriage with a Canaanite, a direct compromise of his covenant identity.

We must take seriously the biblical warnings against being "unequally yoked" (2 Cor 6:14). This applies not just to marriage, but to our deep friendships and business partnerships. Who are your counselors? Who has your ear? If you surround yourself with the wisdom of Adullam, you will soon find yourself with a family full of Canaanites. The results for Judah were catastrophic: sons who were so wicked that God had to intervene directly. Our choices have consequences, and sinful compromises produce death.

But the final application is one of glorious hope. This entire tawdry episode is in the Bible to show us the raw, unvarnished reality of the line from which Christ came. The messianic line is not a gallery of heroes, but a lineup of sinners in desperate need of a Savior. God did not choose Judah because he was worthy. He chose him out of sheer, sovereign grace. And He wove this story of failure, sin, and death into the grand tapestry of redemption. Our own lives are often messy, just like Judah's. We make foolish choices and reap bitter consequences. But our hope is not in our own performance. Our hope is in the Son of Judah, Jesus Christ, who entered into our messy world to redeem it, and who can take the crooked lines of our lives and write a story of His grace.
