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 And Judah saith to Onan, `Go in unto the wife of thy brother, and marry her, and raise up seed to thy brother;'
9 and Onan knoweth that the seed is not [reckoned] his; and it hath come to pass, if he hath gone in unto his brother's wife, that he hath destroyed [it] to the earth, so as not to give seed to his brother;
10 and that which he hath done is evil in the eyes of Jehovah, and He putteth him also to death.
11 And Judah saith to Tamar his daughter-in-law, `Abide a widow at thy father's house, till Shelah my son groweth up;' for he said, `Lest he die -- even he -- like his brethren;' and Tamar goeth and dwelleth at her father's house.
12 And the days are multiplied, and the daughter of Shuah, Judah's wife, dieth; and Judah is comforted, and goeth up unto his sheep-shearers, he and Hirah his friend the Adullamite, to Timnath.
