What will the two witnesses be like during the tribulation?
During the tribulation, the two witnesses will prophesy for 1,260 days, stand as God's messengers—two olive trees and candlesticks—like spiritual lighthouses amid darkness. They will possess protective power, fire from their mouths to devour enemies, authority to shut heaven from rain, turn water to blood, and smite the earth with plagues.
Les explains that these two witnesses are God's messengers for that specific time, described as two olive trees and two candlesticks standing before the God of the earth. The candlestick represents the light it gives, so in the midst of tribulation darkness, wickedness, iniquity, and cataclysmic events, these two men will still be like a spiritual lighthouse. They will prophesy for 1,260 days, or three and a half years. They have special protective power: if anyone tries to hurt them, fire proceeds out of their mouth and devours their enemies; anyone who would hurt them must be killed in that manner. They also have power to shut heaven so it does not rain during their prophecy, similar to Elijah's Old Testament experience, and power over waters to turn them to blood and to smite the earth with all plagues as often as they will, which suggests Moses. Les notes he does not get dogmatic about their identities.
These are the two olive trees, and the two candlesticks standing before the God of the earth.
