'Promised' in the Bible

Moses said to Hobab son of Reuel, the Midianite, Moses' father-in-law, "We are journeying to the place about which the Lord said, 'I will give it to you.' Come with us and we will treat you well, for the Lord has promised good things for Israel."

If a man makes a vow to the Lord or takes an oath of binding obligation on himself, he must not break his word, but must do whatever he has promised.
