[h=1]Psalm 2:7 King James Version (KJV)[/h]7 I will declare the decree: the Lord hath said unto me, Thou art my Son; this day have I begotten thee.

"The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word. "

The Lord sware, and will not repent, Thou art a priest for ever, after the order of Melchisedec. "
Psalm 109 (110 in masoretic)
