Structure of Rev. 6:9-7:17: the 144,000 and the Great Multitude.
Notice how Matthew 24 reinforces the structure enclosing the 5th and 6th seals and the 144,000 and the great multitude. It mentions a great tribulation as well as signs in the sun, moon, and stars occurring just before the Second Coming.
