David continues the story of the journey of the Israelites through the desert. In this part of the story, the Israelites are victorious in war over their enemies.
The large number of people told the Lord's message to others. They are spoken of as if there were a large army. Since this phrase is feminine, some versions translate it as, "the women who announced them ... army." (See: [[rc://en/ta/man/translate/figs-metaphor]])
