'Wedge' in the Bible

When I saw among the spoil a beautiful Babylonian robe, two hundred shekels of silver, and a wedge of gold weighing fifty shekels, then I coveted them and took them. Behold, they are hidden in the ground in the middle of my tent, with the silver under it."

Joshua, and all Israel with him, took Achan the son of Zerah, the silver, the robe, the wedge of gold, his sons, his daughters, his cattle, his donkeys, his sheep, his tent, and all that he had; and they brought them up to the valley of Achor.
