I will make Him my firstborn...

He shall call upon Me and shall say: My Father art Thou, my God, and the helper of my salvation.
And as for Me, I will make him My firstborn, higher than the kings of the earth.
For ever shall I keep for him My mercy, and My covenant shall be faithful unto him.
And I will establish his seed unto ages of ages, and his throne shall be as the days of heaven.
+Prophet David, from The Psalter According to the Seventy, psalm 88.
