Thou hast with thee Shimei - See on Sa2 16:5 (note), etc., and the notes on Sa2 19:18-23 (note).

And behold thou hast with thee Shimei the son of Gera, a Benjamite of Bahurim,.... Of whom, and of his native place; see Gill on Sa2 16:5; he was now at Jerusalem, and so with Solomon, or near at hand; and was on his side, and of his party; see Kg1 1:8; but not to be trusted, or looked upon as a real friend:

which cursed me with a grievous curse, when I went to Mahanaim; a place on the other side Jordan, of which place, and the curses this man cursed David, with, see Sa2 16:7;

but he came down to me at Jordan; after the defeat of Absalom, and when David was returning, and humbled himself to him, and begged his pardon:

and I sware unto him by the Lord, saying, I will not put thee to death with the sword; but this oath was not binding upon his successor, and especially should he commit a new crime.

thou hast with thee Shimei--Though David promised him a pardon, which being enforced by the presence of a thousand followers, could not have been well refused, he warned his son against Shimei as a turbulent and dangerous character. It must not be supposed that in these dying instructions David was evincing a fierce, vindictive spirit. He is rather to be considered as acting in the character of a king and magistrate, in noticing crimes which he had not been in a condition to punish, and pointing out persons of whom Solomon would be under a necessity to rid himself as dangerous to the state. The grateful mention of Barzillai's kindness [Kg1 2:7] was, however, a personal feeling that does honor to the warmth of his heart; and his silence as to Mephibosheth, the son of his beloved Jonathan, would imply the previous death of that prince.
