'Wedge' in the Bible

and I see among the spoil a goodly robe of Shinar, and two hundred shekels of silver, and one wedge of gold, whose weight is fifty shekels, and I desire them, and take them; and lo, they are hid in the earth, in the midst of my tent, and the silver under it.'

And Joshua taketh Achan son of Zerah, and the silver, and the robe, and the wedge of gold, and his sons, and his daughters, and his ox, and his ass, and his flock, and his tent, and all that he hath, and all Israel with him, and they cause them to go up the valley of Achor.
