The Bible Vessel is the ARK of the Covenant, which is a three-letter word. The ARK of the Covenant is a sacred chest described in the Bible as containing the two stone tablets of the Ten Commandments. It was built by Moses and the Israelites at God's command, and it was carried with them during their 40 years of wandering in the desert. The ARK was kept in the Tabernacle and later in the Temple in Jerusalem. It is believed to have been lost or destroyed sometime after 587 BCE.
