Passover

1 “Observe the ^cmonth of Abib and keep the Passover to the Lord your God, for ^din the month of Abib the Lord your God brought you out of Egypt by night. 2 And you shall offer the Passover sacrifice to the Lord your God, from the flock or ^ethe herd, ^fat the place that the Lord will choose, to make his name dwell there. 3 You shall eat no leavened bread with it. ^gSeven days you shall eat it with unleavened bread, the bread of affliction—for you came out of the land of Egypt ^hin haste—that all the days of your life you may remember the day when you came out of the land of Egypt. 4 ⁱNo leaven shall be seen with you in all your territory for seven days, ^jnor shall any of the flesh that you sacrifice on the evening of the first day remain all night until morning. 5 You may not offer the Passover sacrifice within any of your towns that the Lord your God is giving you, 6 but at the place that the Lord your God will choose, to make his name dwell in it, there you shall offer the Passover sacrifice, in the evening at sunset, at the time you came out of Egypt.
