Genesis 38:18

And he said, What pledge shall I give thee? And she said, Thy signet, and thy bracelets, and thy staff that is in thine hand. And he gave it her, and came in unto her, and she conceived by him.

Cross-reference

In Genesis 38:25, Tamar returns the seal and cord to Judah as proof—direct continuation of the pledge given here.

In Genesis 38:26, Judah recognizes his own signet, cord, and staff from verse 18, which leads him to admit his wrongdoing and declare Tamar more righteous.

Leviticus 18:15 explicitly forbids sexual relations with a daughter-in-law, which Judah unknowingly commits here, creating a strong moral contrast.

Leviticus 20:12 prescribes the death penalty for lying with a daughter-in-law, underscoring the gravity of Judah's unwitting sin in this verse.
