'Broken up' in the Bible

And it came to pass, that when the army of the Chaldeans was broken up from Jerusalem for fear of Pharaoh's army,

And in the eleventh year of Zedekiah, in the fourth month, the ninth day of the month, the city was broken up.

Then the city was broken up, and all the men of war fled, and went forth from the city by night by the way of the gate between the two walls, which was by the king's garden; (now the Chaldeans were by the city on all sides:) and they went by the way of the plain.
