The Greek noun exodos (ἔξοδος) means departure, exodus, or exit. It is the Greek title of the second book of Moses. In the New Testament it appears three times. Most significantly, Moses and Elijah discuss Jesus' forthcoming exodos on the Mount of Transfiguration (Luke 9:31).
The exodos of Israel from Egypt becomes the master narrative of redemption. Every great act of divine deliverance echoes it. Jesus discusses His death as an exodos to be fulfilled in Jerusalem (Luke 9:31) — the cross is the ultimate Exodus: liberation from slavery to sin through the blood of the true Passover Lamb (1 Corinthians 5:7). Peter's use of exodos for his own death reframes dying as departure — the door opened by Christ's exodos.
