'Sinned' in the Bible

So it shall be when he becomes guilty in one of these, that he shall confess that in which he has sinned.

‘But if he cannot afford a lamb, then he shall bring to the Lord his guilt offering for that in which he has sinned, two turtledoves or two young pigeons, one for a sin offering and the other for a burnt offering.

‘But if his means are insufficient for two turtledoves or two young pigeons, then for his offering for that which he has sinned, he shall bring the tenth of an ephah of fine flour for a sin offering; he shall not put oil on it or place incense on it, for it is a sin offering.

He shall make restitution for that which he has sinned against the holy thing, and shall add to it a fifth part of it and give it to the priest. The priest shall then make atonement for him with the ram of the guilt offering, and it will be forgiven him.

He is then to bring to the priest a ram without defect from the flock, according to your valuation, for a guilt offering. So the priest shall make atonement for him concerning his error in which he sinned unintentionally and did not know it, and it will be forgiven him.
