This verse from 1 Maccabees 14:21 is expressing the high regard and respect that other nations held for the Jewish people and their leader, Simon Maccabeus. Let's break it down:

"The ambassadors that were sent to our people...": This refers to diplomatic envoys sent from foreign nations to Judea (the land of the Jewish people). The act of sending ambassadors indicates a recognition of Judea's importance and sovereignty.

"...made report to us of your glory and honor...": The ambassadors, upon returning to their own countries, reported favorably about the status of the Jewish people, their leader Simon Maccabeus, and their land. The words "glory and honor" suggest they were impressed by Judea's strength, prosperity, reputation, and the virtue of its leadership. They likely conveyed positive accounts of Judea's newfound independence and stability.

"...and we were glad for their coming": This expresses the Jewish people's satisfaction and joy at the positive reports they received. The fact that foreign ambassadors spoke highly of them boosted their morale, confirmed their hard-won freedom, and demonstrated their growing influence on the world stage. It suggests that Judea was becoming recognized as a significant power.

In essence, this verse highlights:

Judea's growing international recognition: Other nations were acknowledging them as a legitimate and respected entity.
Simon Maccabeus's successful leadership: He had led the Jewish people to independence and established a government that commanded respect from foreign powers.
Positive foreign relations: Judea was not isolated but had established diplomatic ties with other nations, who viewed them favorably.
National pride and vindication: The positive reports from ambassadors confirmed the Jewish people's own sense of accomplishment and validated their struggle for independence.
