4 She conceived again, and bore a son; and she named him Onan. 5 She yet again bore a son, and named him Shelah: and he was at Chezib, when she bore him. 6 Judah took a wife for Er, his firstborn, and her name was Tamar. 7 Er, Judah’s firstborn, was wicked in the sight of Yahweh. Yahweh killed him. 8 Judah said to Onan, “Go in to your brother’s wife, and perform the duty of a husband’s brother to her, and raise up seed to your brother.” 9 Onan knew that the seed wouldn’t be his; and it happened, when he went in to his brother’s wife, that he spilled it on the ground, lest he should give seed to his brother. 10 The thing which he did was evil in the sight of Yahweh, and he killed him also.

Chapter Contents
The profligate conduct of Judah and his family.
This chapter gives an account of Judah and his family, and such an account it is, that it seems a wonder that of all Jacob's sons, our Lord should spring out of Judah, John 8:41. What awful examples the Lord proclaims in his punishments, of his utter displeasure at sin! Let us seek grace from God to avoid every appearance of sin. And let that state of humbleness to which Jesus submitted, when he came to put away sin by the sacrifice of himself, in appointing such characters as those here recorded, to be his ancestors, endear the Redeemer to our hearts.
