[17] But as to Shimei, Solomon commanded that he should build him a house, and stay at Jerusalem, and attend upon him, and should not have authority to go over the brook Cedron; and that if he disobeyed that command, death should be his punishment. He also threatened him so terribly, that he compelled him to take all oath that he would obey. Accordingly Shimei said that he had reason to thank Solomon for giving him such an injunction; and added an oath, that he would do as he bade him; and leaving his own country, he made his abode in Jerusalem. But three years afterwards, when he heard that two of his servants were run away from him, and were in Gath, he went for his servants in haste; and when he was come back with them, the king perceived it, and was much displeased that he had contemned his commands, and, what was more, had no regard to the oaths he had sworn to God; so he called him, and said to him, "Didst not thou swear never to leave me, nor to go out of this city to another? Thou shalt not therefore escape punishment for thy perjury, but I will punish thee, thou wicked wretch, both for this crime, and for those wherewith thou didst abuse my father when he was in his flight, that thou mayst know that wicked men gain nothing at last, although they be not punished immediately upon their unjust practices; but that in all the time wherein they think themselves secure, because they have yet suffered nothing, their punishment increases, and is heavier upon them, and that to a greater degree than if they had been punished immediately upon the commission of their crimes." So Benaiah, on the king's command, slew Shimei.
