1). Given the context, I think it is fair to say these words are directed at the Jewish leaders at His trials.

a). Matthew 26:59-66 Now the chief priests, and elders, and all the council, sought false witness against Jesus, to put him to death;

26:60 But found none: yea, though many false witnesses came, yet found they none. At the last came two false witnesses,

26:61 And said, This fellow said, I am able to destroy the temple of God, and to build it in three days.

26:62 And the high priest arose, and said unto him, Answerest thou nothing? what is it which these witness against thee?

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.

26:64 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.

26:65 Then the high priest rent his clothes, saying, He hath spoken blasphemy; what further need have we of witnesses? behold, now ye have heard his blasphemy.

26:66 What think ye? They answered and said, He is guilty of death.

b). Isaiah 53:6-8  All we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on him the iniquity of us all.

53:7 He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.

53:8 He was taken from prison and from judgment: and who shall declare his generation? for he was cut off out of the land of the living: for the transgression of my people was he stricken.
