'Battle array' in the Bible

Of Zebulun, such as were able to go out in the army, who could set the battle in array, with all kinds of instruments of war, fifty thousand, and who could order [the battle array, and were] not of double heart.

All these being men of war, who could order the battle array, came with a perfect heart to Hebron, to make David king over all Israel: and all the rest also of Israel were of one heart to make David king.

Like the noise of chariots on the tops of the mountains do they leap, like the noise of a flame of fire that devours the stubble, as a strong people set in battle array.
