Leviticus 22:5-7

Living Bible

⁵ or who touches any reptile or other forbidden thing, or who touches anyone who is ceremonially defiled for any reason— ⁶ that priest shall be defiled until evening and shall not eat of the holy sacrifices until after he has bathed that evening. ⁷ When the sun is down, then he shall be purified again and may eat the holy food, for it is his source of life.
