1st Kings 2:38

35 And the king put Benaiah the son of Jehoiada in his room over the host: and Zadok the priest did the king put in the room of Abiathar.

36 And the king sent and called for Shimei, and said unto him, Build thee an house in Jerusalem, and dwell there, and go not forth thence any whither.

37 For it shall be, that on the day thou goest out, and passest over the brook Kidron, thou shalt know for certain that thou shalt surely die: thy blood shall be upon thine own head.

38 And Shimei said unto the king, The saying is good: as my lord the king hath said, so will thy servant do. And Shimei dwelt in Jerusalem many days.

39 And it came to pass at the end of three years, that two of the servants of Shimei ran away unto Achish son of Maachah king of Gath. And they told Shimei, saying, Behold, thy servants be in Gath.

40 And Shimei arose, and saddled his ass, and went to Gath to Achish to seek his servants: and Shimei went, and brought his servants from Gath.

41 And it was told Solomon that Shimei had gone from Jerusalem to Gath, and was come again.
