'Do Good' in the Bible

"For my people [are] foolish, they have not known me. They [are] foolish children, and they do not have insight. They [are] skillful at doing evil, and they do not know [how] to do good."

They [are] like scarecrows in a cucumber field, they cannot speak. Indeed, they must be carried, for they cannot march. You must not be afraid of them, for they cannot do evil; furthermore, to do good [is] not in them."

Can a Cushite change his skin, or a leopard his spots? [Then] you also will be able to do good, [who] are accustomed to doing evil.

And I will rejoice over them to do good [to] them, and I will plant them in this land in faithfulness with all my heart, and with all my inner self."
