'My People' in the Bible

"I've heard Moab's insults and the curses from those Ammonites by which they defame my people and boast about their territory.

Therefore as I'm alive and living," declares the LORD of the Heavenly Armies, the God of Israel, "Moab will surely become like Sodom, and the Ammonites like Gomorrah, a place overrun by weeds and salty marshes, unpopulated forever. The survivors of my people will confiscate their property, and those who remain of my nation will inherit what was theirs.

Indeed, then I will return my people to a pure language so that they all may call upon the name of the LORD, serving him with a united will.
