'Trained' in the Bible

The Reubenites, Gadites, and the half-tribe of Manasseh had 44,760 men in their combined armies, warriors who carried shields and swords, were equipped with bows, and were trained for war.

Some of the Gadites joined David at the stronghold in the desert. They were warriors who were trained for battle; they carried shields and spears. They were as fierce as lions and could run as quickly as gazelles across the hills.

From Judah came 6,800 trained warriors carrying shields and spears.

They and their relatives, all of them skilled and trained to make music to the Lord, numbered two hundred eighty-eight.
