Matthew 22:4

Again he sent forth other servants saying, Tell them that are bidden, Behold I have made ready my dinner; my oxen and my fatlings are killed, and all things are ready: come to the marriage feast.

These other servants and their invitation represent the evangelistic program of the church following the resurrection of Christ. Trench said:

This second summons I take to represent the invitation to the Jewish people, as it was renewed to them at the second epoch of the kingdom, that is, after the resurrection and ascension.[1]

Two things support Trench's view: (1) God was willing to overlook the first blunt rejection of Christ (even his crucifixion), attributing it to ignorance (Acts 3:17). (2) Also, the Jews continued to have a priority in hearing the gospel for a long while after Pentecost, as indicated by Paul's motto, "To the Jew first and also to the Greek" (Romans 1:16). The marvelous solicitation and tenderness of the apostolic preaching, even after the resurrection, shows the forbearance and mercy of God as he yet pleaded with those evil men to acknowledge and receive their true King. That the messengers in this second invitation were the same as the first, in many cases, is no problem. In the most genuine sense, they were "born again" and thus were "other servants." Besides, there were many more of them in the second appeal, including many who were not in the first group.
