'Do Good' in the Bible

and it shall be if thou wilt go with us, - yea it shall be that with the very good wherewith Yahweh shall do us good, will we do good unto thee.

If Balak gave me his house full of silver and gold, I could not go beyond the commandment of Jehovah to do good or bad out of my heart: what Jehovah shall say, that will I speak?
