'Unknowingly' in the Bible

He is then to bring to the priest a ram without blemish from the flock, according to your valuation, for a guilt offering. In this way the priest shall make atonement for him regarding the error which he committed unintentionally and did not know it, and he shall be forgiven.

But if a person unknowingly eats a holy gift [which has been offered to God], then he shall add one-fifth of its value to it and give the holy gift to the priest.
