Matthew Poole's Concise Commentary
Genesis 38:1
GENESIS CHAPTER 38 Judah marries a Canaanitish woman, who bears him three sons, Genesis 38:1. He marries his eldest son to Tamar, Genesis 38:6. He being wicked is slain by God, Genesis 38:7. The second son is commanded to marry her, Genesis 38:8. His wickedness, Genesis 38:9; and death, Genesis 38:10. He promises her his third son, but performs not, Genesis 38:11. She by a subtle practice commits incest with him, Genesis 38:13. He gives her a pledge, Genesis 38:18. She is found with child; Judah commands her to be burnt, Genesis 38:24. She brings to her father the pledge, Genesis 38:25. He acknowledges it; acquits her, and condemns himself, Genesis 38:26. She brings forth two sons, Genesis 38:27. This story is not without difficulty, if we consider how little time is allowed for all the events of this chapter, there being not above twenty-three years between Judah's marriage and the birth of Pharez, yea, and the birth of his sons too, Hezron and Hamul, who are said to go into Egypt with Jacob, Genesis 46:12. But there are two ways proposed for the resolution of it, as the phrase, at that time, may be understood two ways; either,
1. More largely, for the time since Jacob's return from Padan to Canaan, and so the history may be conceived thus, Judah was married some years before the selling of Joseph, though it be here mentioned after it, and so out of its place, as being the foundation of all the following events, which are here placed together, because they followed the selling of Joseph. Judah, and Er, and Onan, and afterwards Pharez, are supposed each to marry and have a child at fourteen years old, which, though unusual, wants not examples both in sacred and profane writers. And they that will quarrel with the Scripture, and question its authority for some such uncustomary occurrences which it relates, show more of impiety than wisdom in it, and shall do well to consider, that God might so order things by his providence, and record such things in his word, upon the same account on which he hath put several other difficult passages in Scripture, partly to try and exercise men's faith, humility, and modesty; and partly to punish the evil minds of ungodly men, and for their sins to lay an occasion of stumbling and cavilling at the Scriptures before them that greedily seek and gladly catch at all such occasions. Or,
2. More strictly, for the time following the sale of Joseph, which seems the more probable way, and so the story lies thus, Judah was now about twenty years old when he married, and the three first years he hath three sons, Er, Onan, and Shelah. The two first marry each when they were about seventeen years old. Three years after both their deaths, and when Shelah had been marriageable a year or two, and was not given to Tamar, Judah lies with Tamar and begets upon her Pharez. But as for Hezron and Hamul, they are said to go into Egypt with Jacob, as also Benjamin's ten sons are said to go with him thither, to wit, in their father's loins, because they were begotten by their father in Egypt, whilst Jacob lived there, of which more in its proper place. Judah went down from his brethren; probably in discontent, upon occasion of quarrels arisen among them about the selling of Joseph, whereof Judah was a great promoter, if not the first mover.
