Genesis 38:25

She sent to her father in law. In passing sentence upon Tamar, Judah had unwittingly condemned himself. His sin, however, consisted not only in giving way to lust, but also in breaking his promise to Tamar (v. 11). This made him personally responsible for the deception she had practiced upon him. His first error had been his own marriage to a Canaanite, in open violation of principle (cf. chs. 24:3; 28:1; 34:14). Furthermore, he certainly knew of the wickedness of his sons; but instead of recognizing the hand of God in their sudden death, he blamed Tamar for it and determined to keep her a childless widow forever.
