The title of the poem, and the use of wings as a symbol for spiritual development, is an allusion to Malachi 4:2: “But unto you that fear my name shall the Sun of righteousness arise with healing in his wings; and ye shall go forth, and grow up as calves of the stall.”
“Lord, who createdst man in wealth and store”
This is an allusion to Adam and Eve in the Garden of Eden .
“if I imp my wings on thine”
The description of God as a falcon, a bird of prey, is an allusion to Isaiah 40:31: “But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.”
“And sing this day thy victories” and “And feel they victorie”
1 Corinthians 15 also uses “victory” to refer to Christ’s resurrection.
Angels' wings are described at several points in the Bible, most notably in Genesis 3:24, Exodus 37:7-9, I Kings 6:23-27, and Luke 1:78-79.
The narrative of both stanzas mirrors the life of Christ, particularly the Crucifixion and the Resurrection.
Christ is described as an angel in Revelations 10:1.
