Psalms 57:6

All David's dependence is upon God. The most eminent believers need often repeat the publican's prayer, "God be merciful to me a sinner." But if our souls trust in the Lord, this may assure us, in our utmost dangers, that our calamities will at length be overpast, and in the mean time, by faith and prayer, we must make him our refuge. Though God be most high, yet he condescends so low, as to take care that all things are made to work for good to his people. This is a good reason why we should pray earnestly. Look which way we will on this earth, refuge fails, no help appears; but we may look for it from heaven. If we have fled from the wrath to come, unto Jesus Christ, he that performed all things needful to purchase the salvation of his people, will do for us and in us all things needful for our enjoyment of it. It made David droop to think there should be those that bore him so much ill-will. But the mischief they designed against him, returned on themselves. And when David was in the greatest distress and disgrace, he did not pray, Lord, exalt me, but, Lord, exalt thine own name. Our best encouragement in prayer, is taken from the glory of God, and to that, more than to our own comfort, we should have regard in all our petitions for mercy.

They have prepared a net for my steps. The enemies of the godly spare no pains, but go about their wicked work with the coolest deliberation. As for each sort of fish, or bird, or beast, a fitting net is needed, so do the ungodly suit their net to their victim's circumstances and character with a careful craftiness of malice. Whatever David might do, and whichever way he might turn, his enemies were ready to entrap him in some way or other. My soul is bowed down. He was held down like a bird in a trap; his enemies took care to leave him no chance of comfort. They have digged a pit before me, into the midst whereof they are fallen themselves. He likens the design of his persecutors to pits, which were commonly dug by hunters to entrap their prey; these were made in the usual path of the victim, and in this case David says, before me, i.e., in my ordinary way. He rejoices because these devices had recoiled upon themselves. Saul hunted David, but David caught him more than once and might have slain him on the spot. Evil is a stream which one day flows back to its source. Selah. We may sit down at the pit's mouth and view with wonder the just retaliations of providence.
