An archaic English adverb meaning long ago, in olden times. Appears in older English translations (and once in the KJV preface) but not directly in the KJV text; cognate concept translated as of old, in days of old, from of old. Hebrew olam (antiquity, long ago) and qedem (former times, ancient days) carry the underlying sense. Psalm 77:5: I have considered the days of old, the years of ancient times. Isaiah 63:9: he bare them, and carried them all the days of old. Micah 5:2: the Messiah's goings forth are from of old, from everlasting. The biblical posture toward yore is not nostalgia (idealizing a past that did not exist) but memory — recalling what God has done as the foundation for trusting what He will do. The discipline of remembering shapes the discipline of hoping. The Psalmist's consideration of days of old is itself a faith-practice.
