The Ark of the Covenant is a sacred chest described in the Bible, specifically in the books of Exodus and Hebrews. It is said to contain the Tablets of the Law, which were given to Moses on Mount Sinai. The Ark is made of acacia wood and covered in gold, featuring two cherubim on its lid, known as the Mercy Seat. The Ark served as a symbol of God's presence among the Israelites during their journey through the wilderness. It was housed in the Tabernacle and later in the Temple built by King Solomon. The Ark played a significant role in various biblical events, including the fall of Jericho.
