Leviticus 5:4-6

Rotherham(i) 4 Or, any person, whensoever he shall swear, speaking unadvisedly with the lips, to harm or to help, as regardeth anything wherein the son of earth may speak unadvisedly by way of oath, and it be hidden from him,––and then, he himself, getting to know it, becometh aware of his guilt, as regardeth any one of these things. 5 Then shall it be, when he becometh aware of his guilt, as regardeth any one of these things, that he shall confess that wherein he hath sinned; 6 and shall bring in as his guilt–bearer unto Yahweh, for his sin which he hath committed, a female from the flock––a lamb or a kid of the goats––as a sin–bearer,––so shall the priest put propitiatory–covering over him, because of his sin.
