For thy servant doth know that I have sinned
He was sensible of it, and sorry for it, and publicly acknowledged it before all the men he brought with him, and before all the servants of David; and as a token of the sincerity of his repentance, and as an earnest of his future fidelity, he made this early submission:
therefore, behold, I am come the first this day of all the house of
Joseph, to go down to meet my lord the king;
but why does he make mention of the house of Joseph, when he was of the tribe of Benjamin? Kimchi says that Benjamin, Ephraim, and Manasseh, were called the house of Joseph; and it may be observed that it is sometimes used for all Israel, as in ( Psalms 80:1 ) ; and he was the first of them that came, inasmuch as he came along with the men of Judah, who came first of all to fetch the king back; or Joseph may stand for the tribes of Israel, as distinct from Judah, and he was the first of them; some of the Jewish writers think he makes mention of the name of Joseph, because as the brethren of Joseph used him ill, and he returned good to them; so though he had used David ill, he hoped he would do as Joseph did, return good for evil; and others represent him as suggesting hereby to David, that all Israel had used him ill, and he worse than them all; and now he was come first, and they were all waiting what he would do to him, that if he received him kindly, all would come and make their peace with him.
