'Infirm' in the Bible

Animals that are blind or fractured or mutilated, or have a sore or a running wound or an itch or scabs, you shall not offer to the Lord nor make an offering of them by fire on the altar to the Lord.

Therefore He brought up against them the king of the Chaldeans who slew their young men with the sword in the house of their sanctuary, and had no compassion on young man or virgin, old man or infirm; He gave them all into his hand.
