Thou thyself - hast cursed others - קללת kalalta, thou hast spoken evil; hast vilified others. O, who is free from evil speaking, from uncharitable speaking; from detailing their neighbor's faults, from whispering, talebearing, and backbiting? Do not wonder if God, in his justice, permit thee to be calumniated, seeing thou hast so frequently calumniated others. See my discourse on Psalm 15:1-5 (note).

For oftentimes also thine own heart knoweth,.... Or "thy conscience", as the Vulgate Latin version, which is as a thousand witnesses; which, if a man attends to, he will be convinced of his own faults, failings, and infirmities, he is frequently in the commission of. Particularly,
that thou thyself likewise hast cursed others; either in heart, or with the tongue; thought ill of them, wished ill to them; spoke contemptibly of them, reviled and reproached them; called them by bad names, and abused them; and said some very hard and severe words concerning them, in a passionate fit, being provoked; and afterwards repented of it, being better informed of the state of the case, or being convinced of the evil of passion and rash speaking; and therefore such should consider the like passions and infirmities of others, and pass over them, and forgive them: so Alshech,
"if thou hast cursed others, and dost desire men should forgive thee, so do thou also forgive;''
see Matthew 6:14. The word "oftentimes", in the first clause, is to be connected, not with the word "knoweth", as if a man often knew this, but with the word "cursed"; suggesting, that a man may be often guilty of this himself, and therefore should be more sparing of his censures of others; see Matthew 7:1.
