I can't find a reference to the Gibeonites and the great crowd before 1986...it could be why some don't remember it. (forgive the formatting...argh)

Many of the Nethinim, who in later years served at Jehovah’s temple, were likely of Gibeonite extraction. Thus the Gibeonites may well foreshadow the “great crowd” that are now rendering God “sacred service day and night in his temple.” (Revelation 7:9, 15) Though living in a Canaanlike world, these at heart are “no part of the world.” Formerly, they had to put up with “crumby” spiritual provisions, such as are found in Christendom’s churches, and they had no “wine” of joy. Coming in contact with God’s people, they have recognized that Jehovah is performing mighty acts through his witnesses. They have made the long trek from Satan’s world in order to exchange tattered ‘garments’ for a new identification as humble servants of Jehovah, clothed with the new personality.—John 14:6; 17:11, 14, 16; Ephesians 4:22-24.

That miraculous rescue of the Gibeonites was prophetic of the modern-day rescue of a “great crowd” of survivors out of the “war of the great day of God the Almighty” at Armageddon. (1 Cor. 10:11; Isa. 28:21, 22) The only book in the Bible that names Armageddon describes also the earthly survivors of the world’s greatest tribulation as a “great crowd.” Just as those ancient Gibeonites, so all those in that “great crowd” need to do something to be rescued from destruction at Armageddon. The Gibeonites took time by the forelock and took advance steps in order to procure a treaty of salvation. If they had waited until Joshua and his executional army found the location of their city and laid siege to it, that would have been too late to escape destruction.

We remember that the Gibeonites of Joshua’s day had their lives spared to serve as slaves to fetch water and to collect firewood for the sacrificial altar in Jehovah’s temple. A thousand and eighteen years after Joshua spared them, the Gibeonites were even privileged to join the Jewish Governor Nehemiah in rebuilding the walls of Jerusalem, in addition to their service at Jehovah’s temple. (Neh. 3:7; 7:25) Quite agreeably with this it is said of the “great crowd,” who were prefigured by the Gibeonites: “That is why they are before the throne of God; and they are rendering him sacred service day and night in his temple; and the one seated on the throne will spread his tent over them.”—Rev. 7:15.

Like those ancient non-Israelite Gibeonites, the “great crowd” of peace-seekers of today surrender themselves in full dedication to Jehovah God through Jesus Christ now before Armageddon breaks out. Therefore the Greater Joshua, Jesus Christ, spares them from destruction in that universal war. Like the remnant of spiritual Israelites, that great crowd loves life. They desire to see an eternity of good days under God’s kingdom. So they follow today the counsel of David and of Peter about peace.

In view of the fact that we live close to the end of the “last days,” it is vital for all persons who want to survive to act without delay, and with complete sincerity. Jesus Christ, who is Jehovah’s executioner today, cannot be tricked as Joshua was. The only way that such persons can enter into an arrangement with him to spare them from execution is for them publicly to declare their faith in Jehovah as the true God. (Compare Acts 2:17-21.) They must also accept Jesus Christ in the roles that God has assigned to him and live thereafter as persons who are not lovers of the way of life of this condemned world. Then they must become humble servants of God, rendering sacred service to him in association with the congregation of his people.—John 17:16; Revelation 7:14, 15
Soon after the Gibeonites took their stand with Jehovah’s people, they came under great pressure. Five kings of the Amorites laid siege to Gibeon to force the inhabitants back onto their side, in opposition to Israel. The Gibeonites dispatched an urgent plea to Joshua for help, and the deliverance that they experienced was one of the most spectacular in all history. Jehovah threw the enemy into confusion, hurled hailstones on them from heaven, and caused the daylight to be extended miraculously until Israel had completely routed the enemy. (Joshua 10:1-14) That rescue of the Gibeonites was prophetic of an even more marvelous deliverance of a great crowd of worshipers of the true God at the universal war of Armageddon. The opportunity to benefit from that deliverance is open to people of every nation if they act wisely now. Are you availing yourself of that opportunity?—Revelation 7:9, 10.
