When I was a child, my congregation sang the first verse of the hymn “Holy, Holy, Holy” as the worship introit every Sunday. Because the congregation sang the verse by heart, I learned it by ear only. For many months I sang:
Holy, holy, holy, Lord God almighty!
Early in the morning our song shall rise to thee.
Holy, holy, holy, merciful and mighty,
God in three persons, bless eternity!
