Psalm 2:
6 Yet have I set my king upon my holy hill of Zion.
7 I will declare the decree: the Lord hath said unto me, Thou art my aSon; this day have I begotten thee.

Hebrews 1:
1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
3 Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;
4 Being made so much better than the angels, as he hath by inheritance obtained a more excellent name than they.
5 For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son?

Hebrews 5:
5 So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee.
6 As he saith also in another place, Thou art a priest for ever after the order of Melchisedec.
