The king said moreover to Shimei, Thou knowest all the wickedness which thine heart is privy to, that thou didst to David my father: therefore the LORD shall return thy wickedness upon thine own head;

And the king said to Semei: Thou knowest all the evil, of which thy heart is conscious, which thou didst to David my father: the Lord hath returned thy wickedness upon thy own head:

And the king said to Shimei, Thou knowest all the wickedness of which thy heart is conscious, which thou didst to David my father; and Jehovah returns thy wickedness upon thine own head;

And the king saith unto Shimei, 'Thou hast known all the evil that thy heart hath known, which thou didst to David my father, and Jehovah hath turned back thine evil on thy head,

And the king said to Shimei, You have knowledge of all the evil which you did to David my father; and now the Lord has sent back your evil on yourself.

And the king said to Shimei: "You know all the evil, of which your heart is conscious, which you did to David, my father. The Lord has repaid your wickedness upon your own head."

The king said moreover to Shimei, (u) Thou knowest all the wickedness which thine heart is privy to, that thou didst to David my father: therefore the LORD shall return thy wickedness upon thine own head;
(u) For though you would deny it, your own conscience accuses you for reviling and doing wrong to my father, (2-Samuel 16:5).

The king said moreover to Shimei,.... Not as another reason for his putting him to death, but to remind him of his former sins, and to observe to him the providence of God in suffering him to fall into others, that justice might take place upon him for them also:
thou knowest all the wickedness which thine heart is privy to, that thou didst to David my father; which conscience must bear witness to, and accuse him of, not only of the words and actions themselves uttered and done by him, but of the malice and wickedness from whence they sprung:
therefore the Lord shall return thy wickedness upon thine own head; the punishment of it; which though not directly inflicted for that, yet in providence was brought about as a just retaliation for it.

He then reminded him of the evil which he had done to his father: "Thou knowest all the evil, which thy heart knoweth (i.e., which thy conscience must tell thee); and now Jehovah returns the evil upon thy head," namely, by decreeing the punishment of death, which he deserved for blaspheming the anointed of the Lord (2-Samuel 16:9).

Thine heart - For which thine own conscience accuseth thee, and there is no need of other witnesses. The Lord - God hath punished thee for thy former wickedness, by suffering thee to expose thyself to thy deserved death.
