And I will give... — Translate, And I will give (omit “power”) to my two witnesses, and they shall... These are the words of God Himself; the omission of the words “and the angel stood” from Revelation 11:1 prevents any confusion of thought on this point. Two witnesses were required for competent evidence (Deuteronomy 17:6; Deuteronomy 19:15, et al.), and there has constantly been a sending forth of God’s chosen messengers in pairs — Moses and Aaron, Elijah and Elisha, besides Joshua and Zerubbabel, alluded to by Zechariah; and in New Testament times our Lord sent forth His disciples “two and two,” as afterwards Paul and Barnabas, or Paul and Silas, went forth to preach. There is, besides the mere mutual support which two can give, a need for the association of two different characters in the same sort of work: the energy and the sympathy, the elucidator of doctrines and the messenger to the conscience, the apologist and the evangelist, the man of thought and the man of action, the Son of Thunder and the Son of Consolation; it is well that in a world-wide work this duality of power should be brought into play. The witnesses prophesy: the word prophesy must surely be allowed a much wider meaning than merely to predict or foretell future events. The compass of their work, as described afterwards, embraces much more than this (see Revelation 11:5-7): they work wonders, showing tokens that remind us of the days of Moses and Aaron; their words are mighty; their life is a testimony.
Their prophesying, or witnessing, extends over forty and two months: a symbolical period, as we have seen, but a period corresponding to that during which other witnesses had witnessed for God. Thus long did Elijah bear witness, under rainless heavens, against the idolatries of Israel; thus long did a greater than Elijah offer the water of life to the Jews, and witness against the hard, unspiritual, worldly religionism of the Pharisee and Sadducee; thus, too, must the witnesses, for God bear testimony during the period that the world- power seems dominant. They are clad in sackcloth — the emblem of mourning (2 Kings 6:30; Jonah 3:4) adopted by the prophets, whose God-taught hearts saw reasons for mourning where shallower minds saw none (Isaiah 20:2, and Zechariah 13:2). Compare the garb of Elijah and John the Baptist (2 Kings 1:8, and Matthew 3:4), whose very apparel and appearance were designed to testify against the evils they saw. “The special witnesses of God, in a luxurious and self-pleasing age, are often marked out from the world by signs of self-denial, of austerity, and even of isolation” (Dr. Vaughan).
