As she was being brought out, she sent word to her father-in-law, “By the man to whom these belong, I am pregnant.” And she said, “Please identify whose these are, the signet and the cord and the staff.”
Judah has sentenced Tamar to death by fire. As they lead her out, she sends him three objects and asks him to name their owner: the judge now holds proof of his own guilt.
The three items she kept
Commentators explain what the word translated "cord" means here:
Morrish Bible DictionaryIn Genesis 38:18, 25 the Hebrew word means "cord," and it was probably the cord by which the signet was hung.
Tamar had asked for these at the moment of the transaction, knowing what a day like this might require.
L. M. GrantWhen he promised to send her a young goat as payment for his fornication, she demanded some security, and he gave her three things that were unmistakably his property (v. 18). From this one occasion she conceived a child.
A judge caught by his own pledge
Judah had passed sentence in the previous verse without a moment's hesitation, and without asking who the other party was.
L. M. GrantHe had no hesitation in condemning her, and passed sentence that she should be burned to death. Evidently he never even thought of the man who was involved in the case. Judah could sin without any question being raised, but he considered that for the very same sin Tamar must be killed!
Judah's own pledge now comes back as evidence against him.
Edwin N. CrossWhat a hypocrite! Judah acts as if he is completely right and without blame, but it is he who has the greater guilt. It was he who caused Tamar to stumble and now he wants her punished… God's Spirit will say, as to his great heir David, "You are the man" (2 Sam. 12:7). He has a double standard, which is not acceptable to a holy God. Judah is ready to condemn Tamar to be burned, but she had secured a pledge from him. She now brought it forward in evidence (v. 25), and it showed Judah's part in the sin before all. This is the way God works. A frank confession will secure His mercy.
What "more righteous than I" does not mean
Judah's admission in the next verse has been used to explain a New Testament phrase, and the comparison sets its limits. Writing on the tax collector who went home justified, one writer draws the line carefully:
William KellyThe sense here is not absolute but comparative justification, just as in Judah's expression in the Greek version of Genesis 38:26: "Tamar is justified rather than I" (that is, more righteous).
Commentators differ on how much credit Judah's words deserve. One reads them as the first sign of a real change: "when Judah exclaimed, 'She is more righteous than I,' it was the evidence of a divine work in his soul" (An Outline of Sound Words). Another is blunter — "he was more guilty than Tamar, for righteousness was not involved in the matter at all" (L. M. Grant).
Measured back to the man who measured it out
Now Judah is the one asked to examine and identify. One commentator sees a pattern in these chapters, writing of Jacob's own deception: "As he measured out, so it was measured to him again. God's government of His people works with great precision" (F. B. Hole). Judah's turn had come:
William KellyIt was not Reuben or any other of the tribal heads, but Judah, who proposed the sale of Joseph. Now he showed in his own house the evil that drew down curse upon curse. In the end its head had to own the sad shame of Tamar, more righteous than himself — the woman he had sentenced to die by fire.
Why this ugly scene is in the Bible
The chapter is not preserved to shame Judah but because the family line to Christ runs straight through it.
C. H. MackintoshHere divine grace triumphs gloriously over man's sin. "It is evident that our Lord was descended from Judah" (Heb. 7:14). But how? "Judah was the father of Perez and Zerah by Tamar" (Matt. 1:3)… The Spirit of God is leading us along the line through which, as to the flesh, Christ came, and in doing so He gives us, as links in the genealogical chain, Tamar and Bathsheba! How clear it is that there is nothing of man in this!
Summary
- Pledge. The cord, signet and staff were Judah's own property. Tamar took them as security and kept them for this moment.
- Exposure. Judah sentenced Tamar without asking who the man was. Her pledge answered that question in public.
- Confession. Judah hears what David later heard: "You are the man." Commentators note that a frank confession secures God's mercy.
- Comparison. "More righteous than I" is comparison, not the justification taught in Romans. Writers differ on what it shows: a real work in Judah's soul, or only his greater guilt.
- Grace. The man who proposed selling Joseph and sentenced Tamar becomes a link in the family line of Christ. Nothing of man is in that chain.
