As bodies of (fresh) water in the Middle East go, the Sea of Kinnereth is quite large. It's about 12½ miles / 20 kilometers from north to south, and 7½ miles / 12 kilometers east to west at its widest. The Jordan River effectively flows through it, entering in the north and exiting in the south.
The popularly-known Sea of Galilee is mentioned in The Bible by 3 other names:
1. The Sea of Kinnereth (or Chinnereth), from its harp-like shape.
2. The Sea of Tiberias.
3. The Lake of Gennesareth.
Much of the ministry of Jesus Christ, and numerous of His miracles (see Miracles Of Jesus Christ) took place in the area of the Sea of Kinnereth.
From the fishermen (see The Fisher) of the Sea of Kinnereth came at least four of The Twelve Apostles - Peter, Andrew, James and John. Jesus stilled the raging storm on the Sea of Kinnereth that was about to swamp their boat. Jesus, and Peter to a limited extent, walked on the water there. Near its shores Jesus fed the five thousand men, women and children from the miraculous multiplication of five loaves of bread and two fish. Mary of Magdala, the first human to see and speak with the Savior after His resurrection, was from the town of Magdala on the western shore of the Sea of Kinnereth.
