To slander; to falsely accuse.

A Psalm of David. LORD, who shall abide in thy tabernacle? who shall dwell in thy holy hill? He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart. He thatBACKBITETH not with his tongue, nor doeth evil to his neighbour, nor taketh up a reproach against his neighbour. ( Psalm 15:1-3 )
