'Flaw' in the Bible

"Observe the month of Abib, keeping the Passover to the LORD your God, because the LORD your God brought you out of Egypt during the night in the month of Abib.

“You must not sacrifice to the Lord your God an ox or sheep with a defect or any serious flaw, for that is detestable to the Lord your God.

They [have] behaved corruptly toward him; [they are] not his children; [this is] their flaw, a generation crooked and perverse.
