1 Kings 2:1-9

Now the days of David drew nigh that he should die; and he charged Solomon his son, saying, I am going the way of all the earth: be thou strong therefore, and show thyself a man; and keep the charge of Jehovah thy God, to walk in his ways, to keep his statutes, and his commandments, and his ordinances, and his testimonies, according to that which is written in the law of Moses, that thou mayest prosper in all that thou doest, and whithersoever thou turnest thyself; that Jehovah may establish his word which he spake concerning me, saying, If thy children take heed to their way, to walk before me in truth with all their heart and with all their soul, there shall not fail thee (said he) a man on the throne of Israel. Moreover thou knowest also what Joab the son of Zeruiah did unto me, even what he did to the two captains of the hosts of Israel, unto Abner the son of Ner, and unto Amasa the son of Jether, whom he slew, and shed the blood of war in peace, and put the blood of war upon his girdle that was about his loins, and in his shoes that were on his feet. Do therefore according to thy wisdom, and let not his hoar head go down to Sheol in peace. But show kindness unto the sons of Barzillai the Gileadite, and let them be of those that eat at thy table; for so they came to me when I fled from Absalom thy brother. And, behold, there is with thee Shimei the son of Gera, the Benjamite, 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 the Jordan, and I sware to him by Jehovah, saying, I will not put thee to death with the sword. Now therefore hold him not guiltless, for thou art a wise man; and thou wilt know what thou oughtest to do unto him, and thou shalt bring his hoar head down to Sheol with blood.
