1 Chronicles 11:10

We have here an account of David's worthies, the great men of his time that served him and were preferred by him. The first edition of this catalogue we had, Sa2 23:8, etc. This is much the same, only that those named here from Ch1 11:41 to the end are added. Observe, I. The connexion of this catalogue with that which is said concerning David, Ch1 11:9. 1. David waxed greater and greater, and these were his mighty men. Much of the strength and honour of great men is borrowed from their servants and depends upon them, which cannot but somewhat diminish pomp and power in the opinion of those that are wise. David is great because he has great men about him; take these away, and he is where he was. 2. The Lord of hosts was with him, and these were the mighty men which he had. God was with him and wrought for him, but by men and means and the use of second causes. By this it appeared that God was with him, that he inclined the hearts of those to come over to him that were able to serve his interest. As, if God be for us none can be against us, so, if God be for us, all shall be for us that we have occasion for.

A CATALOGUE OF HIS WORTHIES. (1Ch. 11:10-47) These . . . are the chief of the mighty men--(See on Sa2 23:8). They are here described as those who held strongly with him (Margin) to make him king, &c. In these words the sacred historian assigns a reason for introducing the list of their names, immediately after his account of the election of David as king, and the conquest of Jerusalem; namely, that they assisted in making David king. In the original form of the list, and the connection in which it occurs in Samuel, there is no reference to the choice of a king; and even in this passage it is only in the clause introduced into the superscription that such a reference occurs [KEIL].
