'Cannot' in the Bible

"'If he cannot afford an animal from the flock, he must bring his penalty for guilt for his sin that he has committed, two turtledoves or two young pigeons, to the Lord, one for a sin offering and one for a burnt offering.

"'If he cannot afford two turtledoves or two young pigeons, he must bring as his offering for his sin which he has committed a tenth of an ephah of choice wheat flour for a sin offering. He must not place olive oil on it and he must not put frankincense on it, because it is a sin offering.

If she cannot afford a sheep, then she must take two turtledoves or two young pigeons, one for a burnt offering and one for a sin offering, and the priest is to make atonement on her behalf, and she will be clean.'"
