Exodus 12:11
10 You must leave nothing until morning, but you must burn with fire whatever remains of it until morning. 11 This is how you are to eat it—dressed to travel, your sandals on your feet, and your staff in your hand. You are to eat it in haste. It is the Lord’s Passover. 12 “‘I will pass through the land of Egypt in the same night, and I will attack all the firstborn in the land of Egypt, both of humans and of animals, and on all the gods of Egypt I will execute judgment. I am the Lord.
Isaiah 52:12
11 Leave! Leave! Get out of there! Don’t touch anything unclean! Get out of it! Stay pure, you who carry the Lord’s holy items. 12 Yet do not depart quickly or leave in a panic. For the Lord goes before you; the God of Israel is your rear guard. 13 Look, my servant will act wisely!20 He will be elevated, lifted high, and greatly exalted—
Notes and References
"... Allusion to this Exodus typology is not always as overt as in these passages. The description of Yahveh as is milhama, 'a warrior,' in Isaiah 42:13 is paralleled only in the Song at the Papyrus Sea (Exodus 15:3), which also ends with the acclamation of Yahveh as king (Exodus 15:18 compare Isaiah 52:7). The prediction that the descendants of the deportees will not leave their exile in haste (52:12), following an explicit reference to the Exodus (verses 3-4), echoes Exodus 12:11 and Deuteronomy 16:3, the command to eat the Passover in haste (behippazon, only in these three texts) ..."
