John 7:6
“My time is not yet come.”
He here seems to me to hint at something other than He expresses; perhaps in their envy they designed to deliver Him up to the Jews; and pointing out this to them, He says, “My time is not yet come,” that is, “the time of the Cross and the Death, why then hasten ye to slay Me before the time?”
“But your time is always ready.”
As though He had said, “Though you be ever with the Jews, they will not slay you who desire the same things with them; but Me they will straightway wish to kill. So that it is ever your time to be with them without danger, but My time is when the season of the Cross is at hand, when I must die.” For that this was His meaning, He showed by what followed.
