Psalms 2:7 - I will declare the decree: the LORD hath said unto me, Thou art my Son; this day have I begotten thee.

Matthew 3:16-17 - And Jesus, when He was baptized, went up straightway out of the water: and, lo, the heavens were opened unto Him, and He saw the spirit of God descending like a dove, and lighting upon Him: and lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.

This pairing of verses leaves no doubt that Jesus Christ is the Son of God.
