'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.

Though Balak would give me his house full of silver and gold, yet could I not go beyond the bidding of Yahweh, to, do good or ill, out of my own heart, - what Yahweh shall speak, that, must I speak?
