'Wedge' in the Bible

when I saw among the spoil a goodly Babylonish mantle, and two hundred shekels of silver, and a wedge of gold of fifty shekels weight, then I coveted them, and took them; and, behold, they are hid in the earth in the midst of my tent, and the silver under it.

And Joshua, and all Israel with him, took Achan the son of Zerah, and the silver, and the mantle, and the wedge of gold, and his sons, and his daughters, and his oxen, and his asses, and his sheep, and his tent, and all that he had: and they brought them up unto the valley of Achor.
