God himself explained the meaning of his name to his faithful servant Moses. When Moses asked about God’s name, Jehovah replied: "I shall prove to be what I shall prove to be." (Exodus 3:14) Rotherham’s translation renders those words: "I Will Become whatsoever I please." So Jehovah can become whatever is needed in order to fulfill his purposes. - What Does the Bible Really Teach? (Published by Jehovah's Witnesses)
