'Able' in the Bible

and two turtledoves, or two young pigeons, such as he is able to afford; and the one shall be a sin offering, and the other a burnt offering.

He shall offer one of the turtledoves, or of the young pigeons, such as he is able to afford,

even such as he is able to afford, the one for a sin offering, and the other for a burnt offering, with the meal offering. The priest shall make atonement for him who is to be cleansed before Yahweh."

This is the law for him in whom is the plague of leprosy, who is not able to afford the sacrifice for his cleansing.

But if he isn't able to get it back for himself, then what he has sold shall remain in the hand of him who has bought it until the Year of Jubilee: and in the Jubilee it shall be released, and he shall return to his property.
