Three terms are used to describe the nation’s disobedience: iniquity (‛āwōn), transgression (pěšǎ), and sins (ḥǎṭṭāṭ). Together they encompass all the misdeeds of the nation. Additionally, each word is in the plural, indicating the depth of sin as well as the effect of the ceremony.
21 And Aaron shall lay both his hands on the head of the live goat, and confess over it all the iniquities of the people of Israel, and all their transgressions, all their sins. And he shall put them on the head of the goat and send it away into the wilderness by the hand of a man who is in readiness.
