Ps 16:10, Mk 1:24, Lk 4:34, Acts 2:27, Acts 3:13-15

The Holy One of God means Christ. In the Old Testament, there is an expression of the Holy One of God. (Ps 16:10, Acts 2:27)

Ps 16:10 For thou wilt not leave my soul in hell; neither wilt thou suffer thine Holy One to see corruption.

Acts 2:27 Because thou wilt not leave my soul in hell, neither wilt thou suffer thine Holy One to see corruption.

Even the demons said that Jesus was the Holy One of God. (Mk 1:24, Lk 4:34)

Mk 1:24 Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art, the Holy One of God.

Lk 4:34 Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art; the Holy One of God.

Jesus is the Holy One of God, the Christ. (Act 3:13-15)

Act 3:13 The God of Abraham, and of Isaac, and of Jacob, the God of our fathers, hath glorified his Son Jesus; whom ye delivered up, and denied him in the presence of Pilate, when he was determined to let him go. 14 But ye denied the Holy One and the Just, and desired a murderer to be granted unto you; 15 And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses.
