The phrase "YHWH, I will become what I choose" is a rephrasing of the name YHWH, often translated as "I Am that I Am" in English. This phrase, found in Exodus 3:14, is understood to mean that God will be whatever is necessary to fulfill His promises and meet the needs of His people. It's not just about God's existence, but also about His active role in shaping events and providing for His followers.
