I speak these things
I am He
Deuteronomy 18:18 (KJV) I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.
John 8:28 Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself; but as my Father hath taught me, I speak these things.
29 And he that sent me is with me: the Father hath not left me alone; for I do always those things that please him.
