Leviticus 4:13-15

¹³If the whole assembly of Israel sins without wanting to sin, and the assembly is unaware that they have sinned and done any of the things which Yahweh has commanded not to be done, and if they are guilty,

¹⁴then, when the sin they have committed becomes known, then the assembly must offer a young bull for a sin offering and bring it before the tent of meeting.

¹⁵The elders of the assembly will lay their hands on the head of the bull before Yahweh, and the bull will be killed before Yahweh.
