Slandering or backbiting. Of this, three sorts of persons are guilty: 1. He that raiseth a false report of his neighbour, Exod. 23:1. Here is a true son of the devil, with malice and lying in conjunction. 2. He who readily reports it, though he knows it to be false, as readily receives, though he is not sure it is true. 3. He that spreads it. This is a very common sin. Tale bearers and whisperers are found every where, whose tongues are swords to stab the reputation of others.
Ye do the devil’s work, who is the accuser of the brethren. Ye are his special errand-bearers, and no doubt, will get such wages as he has to give. Consider that sad passage, Psal. 50:20, 22. “Therefore, speak not evil one of another, brethren. He that speaketh evil of his brother, and judgeth his brother, speaketh evil of the law, and judgeth the law.”

6. Censoriousness, which construes the words and actions of others, always to the worse. Many are of such a waspish nature, that they can suck poison out of the sweetest flowers, and have an evil tale of every person, Matth, 7:1, 2.
