Psalms 15:3 - Joseph Benson’s Commentary on the Old and New Testaments

He backbites not with his tongue Doth not use his tongue to calumniate, or detract from the reputation of any one; speaks evil of no man, nor makes the faults of others the subject of his conversation, much less of his sport or ridicule, nor speaks of them with pleasure, nor at all but for edification. Nor doeth evil Any hurt or injury, willingly or designedly, to his neighbour That is, any man; doth nothing to offend or grieve his spirit, to prejudice the health or ease of his body, to injure him in his estate or secular concerns, in his family or relations; but makes conscience of doing as he would be done by. Nor taketh up a reproach against his neighbour Namely, into his lips or mouth: doth not raise it, or spread and propagate it, or even believe it, without sufficient reason.
