'Forces' in the Bible

In the third year of the rule of Jehoiakim, king of Judah, Nebuchadnezzar, king of Babylon, came to Jerusalem, shutting it in with his forces.

And now I will make clear to you what is true. There are still three kings to come in Persia, and the fourth will have much greater wealth than all of them: and when he has become strong through his wealth, he will put his forces in motion against all the kingdoms of Greece.

And his son will make war, and will get together an army of great forces, and he will make an attack on him, overflowing and going past: and he will again take the war even to his strong place.

So the king of the north will come, and put up earthworks and take a well-armed town: and the forces of the king of the south will make an attempt to keep their position, even the best of his army, but they will not have strength to do so.

And his forces will be completely taken away from before him and broken; and even the ruler of the agreement will have the same fate.
