When Aʹbram was 99 years old, Jehovah appeared to Aʹbram and said to him: "I am God Almighty. Walk before me and prove yourself faultless. 2 I will establish my covenant between me and you, and I will multiply you very, very much." 3 At this Aʹbram fell facedown, and God continued to speak with him, saying: 4 "As for me, look! my covenant is with you, and you will certainly become a father of many nations. 5 Your name will no longer be Aʹbram; your name will become Abraham, for I will make you a father of many nations. 6 I will make you very, very fruitful and will make you become nations, and kings will come from you.
