Dan 9:24-25, Mt 26:63-64, Mk 14:61-62

The Old Testament prophesied when Christ would come. (Dan 9:24-25)

Dan 9:24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy. 25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.

The people of Israel knew that when Christ came, Christ would tell them everything. Jesus revealed to the Samaritan woman that He was the Christ. (Jn 4:25-26)

Jn 4:25 The woman saith unto him, I know that Messias cometh, which is called Christ: when he is come, he will tell us all things. 26 Jesus saith unto her, I that speak unto thee am he.

The people of Israel knew that the Son of God would come as Christ. Jesus revealed to them that He was the Christ. (Mt 26:63-64, Mk 14:61-62)

Mt 26:63 But Jesus held his peace, And the high priest answered and said unto him, I adjure thee by the living God, that thou tell us whether thou be the Christ, the Son of God. 64 Jesus saith unto him, Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.

Mk 14:61 But he held his peace, and answered nothing. Again the high priest asked him, and said unto him, Art thou the Christ, the Son of the Blessed?

62 And Jesus said, I am: and ye shall see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
