Exodus 12

what did dabbing the doorframes with blood have to do with killing Egyptians? Not a lot, except that God told the Hebrews to do it.

God doesn't need great thinkers, writers, or speakers. He doesn't need great warriors or architects. He can do it all better himself. What he wants -- and has always asked -- is obedience.

The Hebrrews had their problems, but this time they listened.
