2 Samuel 16:5,6

When David came to Bahurim The next village in his way to the wilderness; that is, when he came to the territory of it, for he did not reach the place itself till afterward, as is mentioned 2 Samuel 16:14. Thence came out a man, and cursed still as he came Out of an inveterate hatred to David; whom he looked upon as the great enemy of the family of Saul, to which he belonged. And he cast stones, &c. To show his contempt of David and his servants. All his mighty men were on his right hand and on his left This is observed to show the prodigious madness of the man. He could not hurt David, who was so strongly guarded; but he might have been immediately killed himself.
