Bethsaida

Luke 9:10-16  And the apostles, when they had returned, told Him all that they had done. Then He took them and went aside privately into a deserted place belonging to the city called Bethsaida. But when the multitudes knew it, they followed Him; and He received them and spoke to them about the kingdom of God, and healed those who had need of healing. When the day began to wear away, the twelve came and said to Him, “Send the multitude away, that they may go into the surrounding towns and country, and lodge and get provisions; for we are in a deserted place here.” But He said to them, “You give them something to eat.” And they said, “We have no more than five loaves and two fish, unless we go and buy food for all these people.” For there were about five thousand men. Then He said to His disciples, “Make them sit down in groups of fifty.” And they did so, and made them all sit down. Then He took the five loaves and the two fish, and looking up to heaven, He blessed and broke them, and gave them to the disciples to set before the multitude. So they all ate and were filled, and twelve baskets of the leftover fragments were taken up by them.

Geological and geomorphological studies show this valley was part of the Sea of Galilee with series of earthquakes causing silt to accumulate creating the valley and causing the north shore of the Sea of Galilee to recede.

Mark 8: 22-25 Then He came to Bethsaida; and they brought a blind man to Him, and begged Him to touch him. So He took the blind man by the hand and led him out of the town. And when He had spit on his eyes and put His hands on him, He asked him if he saw anything.
And he looked up and said, “I see men like trees, walking.” Then He put His hands on his eyes again and made him look up. And he was restored and saw everyone clearly.
