What does Jeremiah 39:7 mean?

When Zedekiah the king of Judah and all the men of war saw them, then they fled, and went out of the city by night, by the way of the king’s garden, through the gate between the two walls; and he went out toward the Arabah.

But the army of the Chaldeans pursued them, and overtook Zedekiah in the plains of Jericho. When they had taken him, they brought him up to Nebuchadnezzar king of Babylon to Riblah in the land of Hamath; and he pronounced judgment on him.

Then the king of Babylon killed Zedekiah’s sons in Riblah before his eyes. The king of Babylon also killed all the nobles of Judah.

The Chaldeans burned the king’s house, and the houses of the people, with fire, and broke down the walls of Jerusalem.

Then Nebuzaradan the captain of the guard carried away captive into Babylon the residue of the people who remained in the city, the deserters also who fell away to him, and the residue of the people who remained.

But Nebuzaradan the captain of the guard left of the poor of the people, who had nothing, in the land of Judah, and gave them vineyards and fields at the same time.
