Moses 1:21, 24; “And now Satan began to tremble, and the earth shook; and Moses received strength, and called upon God, saying: In the name of the Only Begotten, depart hence, Satan. 24 And it came to pass that when Satan had departed from the presence of Moses, that Moses lifted up his eyes unto heaven, being filled with the Holy Ghost, which beareth record of the Father and the Son.”
Acts 7:22-23, 30-32; “And Moses was learned in all the wisdom of the Egyptians, and was mighty in words and in deeds. 23 And when he was full forty years old, it came into his heart to visit his brethren the children of Israel. 30 And when forty years were expired, there appeared to him in the wilderness of mount Sina an angel of the Lord in a flame of fire in a bush. 31 When Moses saw it, he wondered at the sight: and as he drew near to behold it, the voice of the Lord came unto him, 32 Saying, I am the God of thy fathers, the God of Abraham, and the God of Isaac, and the God of Jacob. Then Moses trembled, and durst not behold.”
Moses lived circa 1500-1390 BC. How did he know the phrase “Only Begotten”?
