What IF?

Revelation 11:3-4 And I will give (as to commission) power (this word is not in the text but was added in) unto My two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth. (8242: worn in mourning and humiliation) 4 These are the two olive trees, and the two candlesticks standing before the God of the earth.
The references describing these two olive trees:
Romans 11:17And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakers of the root and fatness of the olive tree;
Zechariah 4:3 And I answered again, and said unto him, What be these two olive branches which through the two golden pipes empty the golden oil out of themselves? (Clear, pressed out oil)
Zechariah 4:14 Then said he, These are the two anointed ones, that stand by Yahuweh who saves of the whole earth.
