The text is written, as will be observed, in symbolic language.
[415]Under the terms of the law covenant the Jews were required to keep the fiftieth year as a jubilee, and the jubilee year was announced by the blowing of a trumpet.

In the text here under consideration the trumpet symbolizes the message announcing the presence of the Lord, proclaiming the fact that the harvest is due, that the time has come when the saints should be gathered together, because the kingdom of Messiah is at hand.
[416]"Angels" in this text means messengers or servants who make announcement of the presence of the Lord and the incoming of the kingdom.

Such messengers are the truly consecrated Christians who make the announcements to other Christians and to all who have a hearing ear.
It would be reasonable to expect the Lord to have some special messenger, as distinguished from others or general messengers in announcing his presence and the time of the harvest.

And such is the case.

Jesus said that an office had been provided for such a special messenger and that at the time of his second appearing he would appoint some one to that office and give him the responsibility of dispensing meat to the household of faith in due season.
