Thematic Bible: Small offerings accepted from the poor

"But if he is poor and his means are insufficient, then he is to take one male lamb for a guilt offering as a wave offering to make atonement for him, and one-tenth of an ephah of fine flour mixed with oil for a grain offering, and a log of oil, and two turtledoves or two young pigeons which are within his means, the one shall be a sin offering and the other a burnt offering.
