Thence He assumed a Human corresponding to the Divine. He thus united the Divine which means that the Divine took to Itself the Human. Hence it is that He was not only conceived but also born of Jehovah, according to that written in Ps. 2:2, 6.
"I will declare the decree, Jehovah hath said unto Me, Thou art My Son, this day have I begotten Thee". [Ps. 2:7.]
And hence it is that He is the Son of God.
