Of old - See this passage fully explained in the notes at Hebrews 1:10-12. In the beginning; at the first. The phrase used here means literally “to the face;” then, “before” in the order of time. It means here, long ago; of olden time; at the beginning. The meaning is, that the years of God had stretched through all the generations of people, and all the changes which had occurred upon the earth; that at the very beginning he existed, and that he would continue to exist to the very close, unchangeably the same.

25 Of old hast thou laid the foundation of the earth: and the heavens are the work of thy hands.
26 They shall perish, but thou shalt endure:c yea, all of them shall wax old like a garment; as a vesture shalt thou change them, and they shall be changed:
27 But thou art the same, and thy years shall have no end.
