'Troops' in the Bible

So Jehoram crossed over to Zair with all his chariots. Then at night he set out to attack the Edomites who had surrounded him and the chariot commanders, but his troops fled to their tents.

Now the watchman was standing on the tower in Jezreel. He saw Jehu’s troops approaching and shouted, “I see troops!”Joram responded, “Choose a rider and send him to meet them and have him ask, ‘Do you come in peace?’”
