Vayikra 5:7-9

Orthodox Jewish Bible

⁷ And if he be not able to afford a seh (lamb), then he shall bring for his asham (guilt offering, see Sanhedrin 98b on Isa 53; see Isa 53:10 which says that Moshiach’s self-offering will be an asham for his people, cf Isa 53:8), which he hath sinned, two turtledoves, or two young pigeons, unto Hashem; one for a chattat (sin offering), and the other for an olah (burnt offering).

⁸ And he shall bring them unto the kohen, who shall offer that which is for the chattat (sin offering) first, and wring off his head from his neck, but shall not separate it;

⁹ And he shall sprinkle of the dahm of the chattat (sin offering) upon the side of the Mizbe’ach; and the rest of the dahm shall be pressed out at the base of the Mizbe’ach; it is a chattat (sin offering).
