At the beginning of Acts 12, Herod arrests Peter and puts him in jail during the Passover festival (12:3-4). Just as the first Passover in Egypt led to Israel’s liberation from slavery, God replicates that initial Passover night when an angel releases Peter from prison. The disciple’s individual Passover and exodus underscore the continued presence of the God of Israel with the first Jewish followers of Jesus.
While Peter sleeps in prison, an angel of the Lord appears during the night, and tells him, “Gird yourself (ζῶσαι; zosai) and bind on (ὑπόδησαι; hupódesai) your sandals” (Acts 12:8).
The angel’s directions to Peter on this night echo God’s words to the Hebrews on the night they eat the Passover lamb: “Thus you shall eat it with your belt girded around (περιεζωσμέναι; periezosménai), and your sandals (or “bindings,” ὑποδήματα; hupodémata) on your feet” (Exodus 12:11 LXX).
