Psalms 55:19 - Coke's Commentary on the Holy Bible

Even he that abideth of old— Even he who reigns from everlasting. Chandler, after Cocceius. The introducing God as reigning of old, and holding the government of the world from before all ages, has great propriety, and was one of the principal considerations which established David's hope in God, that he would deliver him from this unnatural rebellion. Because they have no changes, is rendered by Chandler, They think of no succeeding changes; that is, "They are prosperous, and have no reverse of fortune, think of none, and fear none; and so fear not God." David's enemies had succeeded, driven him from his capital and throne; thought themselves secure, and had no apprehension or fear from the power or providence of God. Schultens gives the words this sense; "They expect no succession, either of a better life or economy; i.e. a "better state of things here or hereafter." Some render it: They are not changed, and they fear no God. And Mudge reads the whole verse, God shall hear, and he that abideth of old, with whom are no changes, shall humble them, since they fear not God: as much as to say, "That immutable Being (with a glance at the infidelity of men) who was always faithful to his promises and friends, would support him, and humble them."
