'Do Good' in the Bible

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

They are like a palm-tree, of turned work, and speak not: they must needs be borne, because they cannot go. Be not afraid of them; for they cannot do evil, neither is it in them to do good.

Can the Ethiopian change his skin, or the leopard his spots? then may ye also do good, that are accustomed to do evil.
