The proud - The psalmist had before referred to the “proud” as those from whom he had suffered injury, or as having been exposed to their derision. See the notes at Psalms 119:51. He here reverts to another form in which he had suffered from them.
Have forged a lie against me - Compare Job 13:4. The word rendered “forged,” means to patch together; and then it is applied to charges or accusations against anyone, perhaps from their being made up (as they often are) of shreds and patches - hints, small matters, things having no necessary connection in themselves, but brought together as if they pertained to the same transaction - words dropped here and there in conversation, which, being artfully woven together, seem to make out a plausible case against a man. Most slanders are formed and sustained in this way, for it is rare that an absolutely forged slander is uttered against a man, or that a charge is brought which cannot be made to have plausibility from such circumstances as those referred to above. Even the most pure and circumspect cannot always avoid this, for there is something in every man’s life of which a malignant and cunning enemy may take advantage, and which he may weave into a story which some will believe, and which it may not be easy to confute. A malicious man may thus start a slander which may require years to correct, and which may even operate injuriously against a man all his life.
But I will keep thy precepts with my whole heart - Notwithstanding their accusations, and their attempts to turn me away from thee, or to represent me as false and hypocritical. Whatever they may do; whatever reports they may start to my disadvantage, it is my fixed purpose to obey entirely and always thy law. See the notes at Psalms 119:51.
