But know that the LORD hath set apart him that is godly for himself: the LORD will hear when I call unto him. The Lord hath set apart him that is godly - חסיד chasid, the pious, benevolent man. He has marked such, and put them aside as his own property. "This merciful man, this feeling, tender-hearted man, is my own property; touch not a hair of his head!"
