"...The Beginning of the Creation of God"
And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God;" - Revelation 3:14
"The phrase is Jewish, and it is a title the Jews give to Metatron, by whom they sometimes mean the Messiah; so these words in Genesis 24:2, and Abraham said unto his eldest servant of his house, they paraphrase thus:
'and Abraham said unto his servant,' this is Metatron, (or the Mediator,) the servant of God, 'the eldest of his house'; for he is 'the beginning of the creation of God,' who rules over all that he has; for to him the holy blessed God has given the government of all his hosts."
