Jorge,

The two witnesses are not the couple of which you speak.  Please don't be deceived on this.  They may be witnessing for the Lord, but they are NOT the two witnesses of whom scripture speaks.

Here is what the Book of Revelation, chapter 11, verses 3-6,  says about the two witnesses:

 3“And I will grant authority to my two witnesses, and they will prophesy for twelve hundred and sixty days, clothed in sackcloth.” 4These are the two olive trees and the two lampstands that stand before the Lord of the earth.5And if anyone wants to harm them, fire flows out of their mouth and devours their enemies; so if anyone wants to harm them, he must be killed in this way. 6These have the power to shut up the sky, so that rain will not fall during the days of their prophesying; and they have power over the waters to turn them into blood, and to strike the earth with every plague, as often as they desire.
