Exodus 12:5 The animals you choose must be year-old males without defect, and you may take them from the sheep or the goats.
This is a hunter-gatherer culture. Killing animals, sacrificing animals wasn’t unusual. And while making the soon-to-be sacrificed animal an intimate part of the family (as commentary suggests) and putting blood on the lintels and doorposts wasn’t so commonplace, it doesn’t seem to fall too far outside of the norm as to be undoable.
Exodus 12:6 Take care of them until the fourteenth day of the month, when all the members of the community of Israel must slaughter them at twilight.
Rules are easy. They don’t take much mental lifting, especially if there is no room for discussion, argument, understanding. But, again, they can become a slippery slope of obeying the rules at the expense of staying true to the Spirit of God. Being the hands and feet of Jesus takes much more work.
Exodus 12:7 Then they are to take some of the blood and put it on the sides and tops of the doorframes of the houses where they eat the lambs.
Precious Savior, I do not want to be a rule-following automaton. I don’t want to blindly follow rules at the expense of understanding and drawing closer to Your heart. That path is much more difficult, takes much more reading, studying, understanding, work. Help me, Jesus, to become more like You in thought, word, and deed, instead of just safely following the rules. Amen.
Exodus 12:8 That same night they are to eat the meat roasted over the fire, along with bitter herbs, and bread made without yeast.
Have a blessed day.
