'Son of God' in the Bible

The beginning of the gospel of Jesus Christ, the Son of God;

And unclean spirits, when they saw him, fell down before him, and cried, saying, Thou art the Son of God.

and having called with a loud voice, he said, 'What -- to me and to thee, Jesus, Son of God the Most High? I adjure thee by God, mayest thou not afflict me!'

But no one knows when that day or that hour will come; not even the angels in heaven or the Son of God know, but only the Father does.

And when the centurion, which stood over against him, saw that he so cried out, and gave up the ghost, he said, Truly this man was the Son of God.
