'Mustered' in the Bible

So King Joram went out on that day from Samaria, and he mustered all of Israel.

From the city he took one court official who [was] chief officer over the men of war, five men {from the king's council} who were found in the city, the secretary of the commander of the army who mustered the people of the land, and sixty men from the people of the land being found in the city.
