Genesis 38:10 Meaning and Commentary

Genesis 38:10

And the thing which he did displeased the Lord
Being done out of envy to his brother, and through want of affection to the memory of his name; and it may be out of covetousness to get his estate into his own hands, and especially as it frustrated the end of such an usage of marrying a brother's wife; which appears to be according to the will of God, since it afterwards became a known law of his; and it was the more displeasing, as it was not only a check upon the multiplication of Abraham's seed as promised, but since the Messiah was to come from Judah. This was doing all to hinder it that lay in his power: wherefore he slew him also;
in like manner as he had slain his brother, ( Genesis 38:7 ) .

Genesis 38:10 In-Context

8 Then Judah said to Onan, Go in to thy brother's wife, and fulfil to her the brother-in-law's duty, and raise up seed to thy brother.

9 But when Onan knew that the seed should not be his own, it came to pass when he went in to his brother's wife, that he spilled [it] on the ground, in order to give no seed to his brother.

10 And the thing which he did was evil in the sight of Jehovah, and he slew him also.

11 And Judah said to Tamar his daughter-in-law, Remain a widow in thy father's house, until Shelah my son is grown; for he said, Lest he die also, as his brethren. And Tamar went and remained in her father's house.

12 And as the days were multiplied, Judah's wife, the daughter of Shua, died. And Judah was comforted, and he went up to his sheep-shearers, to Timnah, he and his friend Hirah the Adullamite.
