LEV 5:15

15 If a nefesh commit a ma'al [(trespass)], and sin through ignorance [(unintentionally)], in the holy things of Hashem; then he shall bring for his asham unto Hashem a ram tamim out of the flocks, with thy estimation by shekels of kesef, after the Shekel HaKodesh [(the Shekel of the Sanctuary)], for an asham [(trespass or guilt offering)].
