NASB Translation
Hosea (3), Hoshea (12), Joshua (1).
The angel said," You shall call His name Yeshua, for He shall save His people from their sins".
Amen means faithful and true.
Jesus is the Amen, the hidden God in heaven, who was worshipped by the Egyptians [after they were taught about Him by Abraham, from the Book of Enoch, as Abraham said He did when Sarah was returned by Pharoah's wise men, who asked Abraham to teach them "wisdom, values and truth"; so Abraham said he "read to them from the Book of Enoch", -which is in the Genesis Apocryphon manuscripts in the Dead Sea Scrolls].
Paul said all men once knew, but changed the truth of God into a lie, and so the Egyptians evolved a lie about God, Amen, the hidden God in heaven who created all things, whom they wrote of as if it was New Testament truth,before they changed His truth into a lie, because they got the Truth of the Amen, from Abraham who got it from the Book of Enoch, which He got from Noah and Shem. -they were contempories, and Shem outlived Abraham and was the Priest of the Most High God in Salem, who blessed Abram with the blessing of "firstborn" and "high priest"......
Jesus tells us He is "The Amen" -the same once hidden but now revealed "Amen" whom ancient Egypt worshiped and who backslid from and changed His truth into a lie, like all men do as Paul said in Rmans 1.
God promises to restore Egypt to Himself, just as He will restore Israel to Himself...
