It’s very plausible that the two witnesses of Revelation 11 are Judaism and Christianity and/or the Old Testament and New Testament

Revelation 11:3 says, “And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.” (Rev. 11:3). Jesus came to earth, conceived by the Holy Ghost, in the virgin, Mary, born of the virgin, Mary, espoused to Joseph (Matt. 1:18-25). He had brothers and sisters (Mark 6:3). He started His earthly ministry at about the age of thirty (Luke 3:23). And for three and a half years, He healed, did miracles, and forgave sins. And at Passover in 31 A.D., Jesus died on the cross for the forgiveness of our sins, He was buried, and the third day He arose to give us the hope and promise of eternal life in His Holy name. Alleluia and praise the LORD. Amen and Amen.

Simplifying the Old Testament

Jesus said that all the law and the prophets hang on two commandments; love God with all your heart, with all your soul and with all your mind, and love your neighbour as yourself (Matt. 22:37-40). Jesus simplified it even further and said, “Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.” (Matt. 7:12). Jesus came to earth, conceived by the Holy Ghost, in the virgin, Mary, born of the virgin, Mary, espoused to Joseph (Matt. 1:18-25). He had brothers and sisters (Mark 6:3). He started His earthly ministry at about the age of thirty (Luke 3:23). And for three and a half years, He healed, did miracles, and forgave sins. And at Passover in 31 A.D., Jesus died on the cross for the forgiveness of our sins, He was buried, and the third day He arose to give us the hope and promise of eternal life in His Holy name. Alleluia and praise the LORD. Amen and Amen.
