'It is I' in the Bible

But straightway Jesus spake unto them, saying, Be of good cheer; it is I; be not afraid.

For they all saw him, and were troubled. And immediately he talked with them, and saith unto them, Be of good cheer: it is I; be not afraid.

Then said he unto the disciples, It is impossible but that offences will come: but woe unto him, through whom they come!

Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have.

But he saith unto them, It is I; be not afraid.

For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.
