Genesis 38:8-9

8 And Judah said unto Onan, Go in unto thy brother's wife, and marry her, and raise up seed to thy brother.
9 And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother's wife, that he spilled it on the ground, lest that he should give seed to his brother.

Genesis 38:8-9 Meaning and Commentary

INTRODUCTION TO GENESIS 38

This chapter is wholly taken up with matters relating to Judah, the fourth son of Jacob, from whom the Jews have their name, and from whom Christ sprung: it treats of his marriage with a Canaanitess, his children by her, their character and end, Ge 38:1-11; of his incest with his daughter-in-law, though unknown by him, Ge 38:12-23; of his resentment against her, when he heard she was with child, and his confusion when he found it was by himself, Ge 38:24-26; and of the birth of twins by her, named Pharez and Zarah, Ge 38:27-30.
