'Do Good' in the Bible

For my people are foolish, me they have not known, Foolish sons are they, yea, they are not intelligent, Wise are they to do evil, And to do good they have not known.

As a palm they are stiff, and they speak not, They are surely borne, for they step not, Be not afraid of them, for they do no evil, Yea, also to do good is not in them.

Doth a Cushite change his skin? and a leopard his spots? Ye also are able to do good, who are accustomed to do evil.
