'Troops' in the Bible

The king was enraged, so he sent out his troops, destroyed those murderers, and burned down their city.

When the dispute became violent, the commander feared that Paul might be torn apart by them and ordered the troops to go down, rescue him from them, and bring him into the barracks.

When this man had been seized by the Jews and was about to be killed by them, I arrived with my troops and rescued him because I learned that he is a Roman citizen.

The number of mounted troops was 200 million; I heard their number.
