John 8:28 - Clarke's commentary and critical notes on the Bible

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. When ye have lifted up - When ye have crucified me, and thus filled up the measure of your iniquities, ye shall know that I am the Christ, by the signs that shall follow; and ye shall know that what I spoke is true, by the judgments that shall follow. To be lifted up, is a common mode of expression, among the Jewish writers, for to die, or to be killed.
