2 Samuel 19:23

Thou shalt not die, to wit, this day, as Abishai desireth; nor whilst I live, nor by my hands, as it is repeated and explained, 1 Kings 2:8; nor for this cause alone. For though David gave order to Solomon for his punishment after his death; nor was it fit for the public good that such a horrid crime should go unpunished; yet he would not have him punished for this fault alone, but for some other capital crime, which he presumed Shimei's temper would easily betray him to, and Solomon's deep wisdom would easily find out, 1 Kings 2:9. The king sware unto him, that he would not put him to death with the sword, as it is expressed, 1 Kings 2:8.
