'Able' in the Bible

And if the disease comes out all over his skin, from his head to his feet, as far as the priest is able to see,

And if he is poor and not able to get so much, then he may take one male lamb as an offering for wrongdoing, to be waved to take away his sin, and one tenth part of an ephah of the best meal mixed with oil for a meal offering, and a log of oil;

And two doves or two young pigeons, such as he is able to get; and one will be for a sin-offering and the other for a burned offering.

And he will make an offering of one of the doves or the young pigeons, such as he is able to get;

This is the law for the man who has the disease of the leper on him, and who is not able to get that which is necessary for making himself clean.

But if he is not able to get it back for himself, then it will be kept by him who gave a price for it, till the year of Jubilee; and in that year it will go back to its first owner and he will have his property again.

And if your brother becomes poor and is not able to make a living, then you are to keep him with you, helping him as you would a man from another country who is living among you.
