A person shares in the sin of a slanderer when he listens and accepts it. Adam Clarke and the Psalmist agree ...
Psalms 15:3 PP3
“Reader, drive the slanderer of your neighbour far away from you: ever remembering that in the law of God, as well as in the law of the land, "the receiver is as bad as the thief." (from Adam Clarke Commentary)
"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 that backbiteth not with his tongue**, nor doeth evil to his neighbour, **nor taketh up a reproach against his neighbour.**
In whose eyes a vile person is contemned; but he honoureth them that fear the LORD.
He that sweareth to his own hurt, and changeth not. He that putteth not out his money to usury, nor taketh reward against the innocent. He that doeth these things shall never be moved." Psa 15:1-5 (KJV)
