An object used to keep a ship or boat in one place in the water. An anchor is attached to a ship by a cable or chain. When it is thrown overboard, its weight and ability to dig into the sea bottom keep the boat from drifting.
Anchors were used many centuries before the time of Christ. They began as simple stone weights. They developed into wooden hooks weighted with lead or stone.
Not long after the time of Christ, iron anchors of the familiar modern shape were used. Anchors are mentioned in Luke’s account of the apostle Paul’s voyage to Rome (Acts 27:13, 29–30, 40). Hebrews 6:19 uses “anchor” as a symbol to indicate the stability of God’s promise of salvation to those who believe in him.
