1 Kings 2:8-9

BBE(i) 8 Now you have with you Shimei, the son of Gera the Benjamite of Bahurim, who put a bitter curse on me on the day when I went to Mahanaim; but he came down to see me at Jordan, and I gave him my oath by the Lord, saying, I will not put you to death by the sword. 9 But do not let him be free from punishment, for you are a wise man; and it will be clear to you what you have to do with him; see that his white head goes down to the underworld in blood.
