'Trained' in the Bible

And some of the Gadites, siding with David, went to his strong place in the waste land, great and strong men, trained for war, expert in the use of arms, whose faces were like the faces of lions, and they were quick-footed like roes on the mountains;

And the number of them, with their brothers who were trained and expert in making melody to the Lord, was two hundred and eighty-eight.

And see, there are the divisions of the priests and Levites for all the work of the house of God; and every trained and expert workman will be ready to do for you whatever is needed; and the captains and the people will be under your orders in everything.
