Prophet David: I will seek the Lord.

 My heart said unto Thee: I will seek the Lord. My face hath sought after Thee; Thy face, O Lord, will I seek.

+David the Prophet and King, from The Psalter according to the Seventy, psalm 26.

Prophet David: The greatness of man

What is man, that Thou art mindful of him? Or the son of man, that Thou visitest him? Thou hast made him a little lower than the angels; with glory and honor hast Thou crowned him, and Thou hast set him over the works of Thy hands. All things hast Thou subjected under his feet, sheep, and all oxen, yea, and the beasts of the field. The birds of the air, and the fish of the sea, the things that pass through the paths of the sea. O Lord, how wonderful is Thy Name in all the earth.
+David the Prophet and King, from The Psalter according to the Seventy, psalm 8.

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.
