Webster(i)
8 And behold, thou hast with thee Shimei the son of Gera, a Benjaminite of Bahurim, who cursed me with a grievous curse in the day when I went to Mahanaim: but he came down to meet me at Jordan, and I swore to him by the LORD, saying, I will not put thee to death with the sword.
9 Now therefore hold him not guiltless: for thou art a wise man, and knowest what thou oughtest to do to him; but his hoary head do thou bring down to the grave with blood.
