Vayikra 5:7

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).
