2 Samuel 13:13

My shame - Better, “my reproach.” Compare Genesis 30:23; Gen 34:14; 1 Samuel 11:2.

Speak unto the king ... - It cannot be inferred with certainty from this that marriages were usual among half brothers and sisters in the time of David. The Levitical law forbade them (marginal reference), and Tamar may have merely wished to temporize. On the other hand, the debasing and unhumanizing institution of the harem, itself contrary to the law of Moses Deuteronomy 17:17, may well have led to other deviations from its precepts, and the precedent of Abraham Genesis 20:12 may have seemed to give some sanction to this particular breach of it.
