Exodus 12:6-8

6Take care of it until the fourteenth ⌞day⌟ of this month. “Then at dusk, all the assembled people from the community of Israel must slaughter their animals.

7They must take some of the blood and put it on the sides and tops of the doorframes of the houses where they will eat the animals.

8The meat must be eaten that same night. It must be roasted over a fire and eaten with bitter herbs and unleavened bread.
