חֹשֶׁן

Wikipedia EN

The priestly breastplate (Hebrew: חֹשֶׁן‎ ẖošen) was a sacred breastplate worn by the High Priest of the Israelites, according to the Book of Exodus. In the biblical account, the breastplate is sometimes termed the breastplate of judgment, because the Urim and Thummim were placed within it. These stones were, at times, used to determine God's will in a particular situation (see Exodus 28:30). Using these stones did not always determine God's will (see 1 Samuel 28:6)
