'Prepare' in the Bible

His sons will prepare for war, assembling an army of considerable force. One of them will come on forcefully, overflowing, passing through, and waging war up to his own fortress.

“With a large army he will stir up his power and his courage against the king of the South. The king of the South will prepare for battle with an extremely large and powerful army, but he will not succeed, because plots will be made against him.
