3 He that backbiteth not with his tongue, nor doeth evil to his neighbour, nor taketh up a reproach against his neighbour.
3 whose tongue utters no slander, who does no wrong to a neighbor, and casts no slur on others;
3 who does not slander with his tongue and does no evil to his neighbor, nor takes up a reproach against his friend;
3 "Don't hurt your friend, don't blame your neighbor;
3 He who does not backbite with his tongue, Nor does evil to his neighbor, Nor does he take up a reproach against his friend;
3 Those who refuse to gossip or harm their neighbors or speak evil of their friends.
Matthew Henry's Commentary on Psalm 15:3
The way to heaven, if we would be happy, we must be holy. We are encouraged to walk in that way.
Here is a very serious question concerning the character of a citizen of Zion. It is the happiness of glorified saints, that they dwell in the holy hill; they are at home there, they shall be for ever there. It concerns us to make it sure to ourselves that we have a place among them. A very plain and particular answer is here given. Those who desire to know their duty, will find the Scripture a very faithful director, and conscience a faithful monitor. A citizen of Zion is sincere in his religion. He is really what he professes to be, and endeavours to stand complete in all the will of God. He is just both to God and man; and, in speaking to both, speaks the truth in his heart. He scorns and abhors wrong and fraud; he cannot reckon that a good bargain, nor a saving one, which is made with a lie; and knows that he who wrongs his neighbour will prove, in the end, to have most injured himself. He is very careful to do hurt to no man. He speaks evil of no man, makes not others' faults the matter of his common talk; he makes the best of every body, and the worst of nobody. If an ill-natured story be told him, he will disprove it if he can; if not, it goes no further. He values men by their virtue and piety. Wicked people are vile people, worthless, and good for nothing; so the word signifies. He thinks the worse of no man's piety for his poverty and mean condition. He reckons that serious piety puts honour upon a man, more than wealth, or a great name. He honours such, desires their conversation and an interest in their prayers, is glad to show them respect, or do them a kindness. By this we may judge of ourselves in some measure. Even wise and good men may swear to their own hurt: but see how strong the obligation is, a man must rather suffer loss to himself and his family, than wrong his neighbour. He will not increase his estate by extortion, or by bribery. He will not, for any gain, or hope of it to himself, do any thing to hurt a righteous cause. Every true living member of the church, like the church itself, is built upon a Rock. He that doeth these things shall not be moved for ever. The grace of God shall always be sufficient for him. The union of these tempers and this conduct, can only spring from repentance for sin, faith in the Saviour, and love to him. In these respects let us examine and prove our own selves.
