How confident are you the 144,000 Jewish virgins are sealed at the beginning of the Tribulation? I have always understood the 144,000 were sealed after the first, second, third, fourth, fifth and the six seal were opened by the Lamb (Jesus). Rev. 7: 3-8 describes the sealing of the 144,000. Then in Rev. 7:14 describes the multitude that came out of the Great Tribulation which is the last 3 ½ years isn’t it?
