A redemption verb emphasizing the payment of a price to secure release. Unlike gaal (H1350, the kinsman-redeemer), padah focuses on the transactional aspect — a ransom is paid, a substitute takes the place of the condemned. Used of redeeming firstborn children, redeeming slaves, and God's mighty deliverance of Israel from Egypt.
Padah establishes the ransom-framework that runs through all of Scripture. God padah-ed Israel from the 'iron furnace' of Egypt with an outstretched arm. The Psalmist cries to God as the one who padah-s the soul from Sheol. The NT fulfillment is explicit in Mark 10:45 — the Son of Man came to give his life as a 'ransom' (lytron) for many.
