[207] When David was at Bahurim, a place so called, there came out a kinsman of Saul's, whose name was Shimei, and threw stones at him, and gave him reproachful words; and as his friends stood about the king and protected him, he persevered still more in his reproaches, and called him a bloody man, and the author of all sorts of mischief. He bade him also go out of the land as ,an impure and accursed wretch; and he thanked God for depriving him of his kingdom, and causing him to be punished for what injuries he had done to his master [Saul], and this by the means of his own son. Now when they were all provoked against him, and angry at bin;, and particularly Abishai, who had a mind to kill Shimei, David restrained his anger. "Let us not," said he, "bring upon ourselves another fresh misfortune to those we have already, for truly I have not the least regard nor concern for this dog that raves at me: I submit myself to God, by whose permission this man treats me in such a wild manner; nor is it any wonder that I am obliged to undergo these abuses from him, while I experience the like from an impious son of my own; but perhaps God will have some commiseration upon us; if it be his will we shall overcome them." So he went on his way without troubling himself with Shimei, who ran along the other side of the mountain, and threw out his abusive language plentifully. But when David was come to Jordan, he allowed those that were with him to refresh themselves; for they were weary.
