Another new class has already been identified, the "Nethinim," the "given ones" in a 1992 WT article.
4/15/92 WT
p. 12 Jehovah’s Provision, the "Given Ones"Further explanation was given in the 1993 Yearbook p 254.
As explained in this issue of The Watchtower, there is a group serving with spiritual Israel today that is comparable to the Nethinim and the sons of the servants of Solomon who returned from Babylonian exile with the Jewish remnant; those non-Israelites even outnumbered the returning Levites. (Ezra 2:40-58; 8:15-20) ‘Given ones’ from among today’s great crowd are mature Christian men who have had considerable experience as a result of caring for oversight in branches, in the traveling work, and among the 66,000 congregations now established throughout the earth.
"At the Brooklyn headquarters of Jehovah’s Witnesses, some ‘given ones’ have served for a great many years. These include mature overseers from the great crowd who have gained a wealth of ability and experience. Thus, the Governing Body has selected a few of such overseers to assist in the meetings of the Governing Body’s committees. These are not necessarily the men with the longest record of service. Rather, they are mature, experienced men with qualifications that fit them for giving assistance in particular fields. Their being assigned to work with a committee does not give them a special status (they must think we are idiots). As Jesus said concerning his disciples, ‘all you are brothers.’ (Matthew 23:8) However, much will be entrusted to these men, and consequently ‘much will be demanded’ of them.—Luke 12:48.
In the 7/1/95 WT p. 22 this was brought out again.
Moreover, with the great crowd increasing by the hundreds of thousands each year, there is an ever-growing need for oversight. At one time this was handled exclusively by anointed Christians. Now, oversight of most congregations, as well as circuits, districts, and branches, has of necessity been entrusted to the other sheep. In 1992 a few of these were given the privilege of attending meetings of committees of the Governing Body and serving as nonvoting helpers. Still, the other sheep remain loyal to their anointed fellow Christians and feel privileged to support them as Jehovah’s faithful and discreet slave.—Matthew 25:34-40.
And in the 5/15/97 WT
p. 20In keeping with his administration of things, Jehovah is progressively moving "to gather all things together again in the Christ." As far as "the things in the heavens" are concerned, his purpose approaches completion. The uniting of Jesus with all the 144,000 in heaven for "the marriage of the Lamb" is near. Hence, more and more longtime, mature brothers of the other sheep, representing "the things on the earth," have had delegated to them weightier responsibilities in support of their anointed brothers.
The WTS wavers back and forth about whether any of the anointed will still be on earth when the end comes. Currently, they believe they will be and consider a "point of evidence" that we are in the last days.
