'Unfit' in the Bible

Nor shall you offer as the food of your God any such [animals obtained] from a foreigner, because their corruption and blemish makes them unfit; there is a defect in them, they shall not be accepted for you.’”

Let the guilt fall on the head of Joab and on all his father’s house (family); and may there never disappear from the house of Joab one who suffers with a discharge or one who is a leper or one who walks with a crutch [being unfit for war], or one who falls by the sword, or one who lacks food.”
