Genesis 35:22 - Matthew Poole's English Annotations on the Holy Bible

This was a horrid incest; for concubines were a sort of wives. See Genesis 22:24, Genesis 25:1. Israel heard it, and doubtless sadly resented it, both in Reuben, as appears from Genesis 49:4 1 Chronicles 5:1,2; and in Bilhah, whose bed without question he forsook upon it, as afterwards David did in the like case. See 2 Samuel 16:22, 2 Samuel 20:3. Yet here is no mention of Jacob's reproof of it, nor any censure of Moses added to it; possibly to teach us, that we are not to approve of every fact which is mentioned in Scripture without censure, and that the miscarriages of professors of religion are rather to be silently bewailed than publicly reproached, lest religion should suffer by it. The sons of Jacob were twelve, which were heads of the twelve tribes; therefore his daughter Dinah is not here mentioned, because she was not the head of a tribe.
