'Flaw' in the Bible

“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.

No man in all Israel was as handsome and highly praised as Absalom. From the sole of his foot to the top of his head, he did not have a single flaw.

For my arguments are without flaw;one who has perfect knowledge is with you.
