2 Kings 2:10

And Elias said, Thou hast put me to a stand by this request. If thou seest me taken up from thee, it shall be so to thee; but if not; it cannot be granted.

And Eliu said, Thou hast asked a hard thing: if thou shalt see me when I am taken up from thee, then shall it be so to thee; and if not, it shall not be so.
