So David and his men went by the way: and Shimei went along on the hill side over against him, and cursed as he went, and threw stones at him, and cast dust.
And when king David came to Bahurim, behold, there came out thence a man of the family of the house of Saul, whose name was Shimei, the son of Gera: he came out, and cursed still as he came.
Then said Abishai the son of Zeruiah unto the king, Why should this dead dog curse my lord the king? let me go over, I pray thee, and take off his head.
And he said unto his men, The LORD forbid that I should do this thing unto my lord, the LORD'S anointed, to put forth mine hand against him, seeing he is the LORD'S anointed.
