Matthew 24:9-10, 12-13

Matthew 24:9: “Then shall they" [The deceived] "deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for my name's sake.”

Matthew 24:10: “And then shall many" [The deceived] "be offended,” [Of the testimony of the 144,000] “and shall betray one another, and shall hate one another.”

Matthew 24:12: “And because iniquity" [Sin] "shall abound, the love of many shall wax cold.”

Matthew 24:13: “But he” [The Elect] “that shall endure unto the end," [The Great Earthquake/The Day of the Lord] "the same shall be saved.”

Revelation 6:9-11

Revelation 6:9: “And when he” [Christ] “had opened the fifth seal,” [Christ opened the fifth seal of the book that he received from the Most High] “I” [John] “saw under the altar the souls of them" [Those of the 144,000] "that were slain for the word of God, and for the testimony which they held:”

Revelation 6:10: “And they" [Those of the 144,000 slain for the word of God] "cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?”

Revelation 6:11: “And white robes were given unto every one of them;" [Those of the 144,000 slain for the word of God] "and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren," [The rest of the 144,000] "that should be killed as they were, should be fulfilled.” The Two Witnesses’ death fulfills the killing of the 144,000.

The vision of the Fifth Seal represents the killing of the 144,000 and their reward (white robes), they will be killed during the Great Tribulation.
