'Array' in the Bible

Abijah joined battle with an army of valiant men of war, even four hundred thousand chosen men: and Jeroboam set the battle in array against him with eight hundred thousand chosen men, who were mighty men of valor.

Then Asa went out to meet him, and they set the battle in array in the valley of Zephathah at Mareshah.

When he had taken counsel with the people, he appointed those who should sing to Yahweh, and give praise in holy array, as they went out before the army, and say, Give thanks to Yahweh; for his loving kindness endures forever.
