'Do Good' in the Bible

For my people is foolish, they have not known me; they are sottish children, and they have no intelligence; they are wise to do evil, but to do good they have no knowledge.

They are as a palm-column of turned work, and they speak not; they are carried, for they cannot go. Be not afraid of them; for they cannot do evil, neither also is it in them to do good.

Can an Ethiopian change his skin, or a leopard his spots? Then may ye also do good, who are accustomed to do evil.
