2 Chronicles 14:8 (KJV)

And he built fenced cities in Judah: for the land had rest, and he had no war in those years; because the Lord had given him rest.

Therefore he said unto Judah, Let us build these cities, and make about them walls, and towers, gates, and bars, while the land is yet before us; because we have sought the Lord our God, we have sought him, and he hath given us rest on every side. So they built and prospered.

And Asa had an army of men that bare targets and spears, out of Judah three hundred thousand; and out of Benjamin, that bare shields and drew bows, two hundred and fourscore thousand: all these were mighty men of valour.

And there came out against them Zerah the Ethiopian with an host of a thousand thousand, and three hundred chariots; and came unto Mareshah.

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