Sea of Galilee - This was also called the Sea of Tiberias and the Lake of Gennesareth, and also the Sea of Chinnereth, Numbers 34:11; Deuteronomy 3:17; Joshua 12:3. Its form is an irregular oval, with the large end to the north. It is about 14 miles in length, and from 6 miles to 9 miles in width. It is about 600 feet lower than the Mediterranean, and this great depression accounts for some of its special phenomena. There is no part of Palestine, it is said, which can be compared in beauty with the environs of this lake. Many populous cities once stood on its shores, such as Tiberias, Bethsaida, Capernaum, Chorazin, Hippo, etc. The shores are described by Josephus as a perfect paradise, producing every luxury under heaven at all seasons of the year, and its remarkable beauty is still noticed by the traveler. “Seen from any point of the surrounding heights, it is a fine sheet of water a burnished mirror set in a framework of surrounding hills and rugged mountains, which rise and roll backward and upward to where hoary Hermon hangs the picture on the blue vault of heaven.” The lake is fed mainly by the Jordan; but besides this there are several great fountains and streams emptying into it during the rainy seasons, which pour an immense amount of water into it, raising its level several feet above the ordinary mark. See The Land and the Book (Thomson), vol. ii. p. 77. Lieutenant Lynch reports its greatest ascertained depth at 165 feet. The waters of the lake are sweet and pleasant to the taste, and clear. The lake still abounds with fish, and gives employment, as it did in the time of our Saviour, to those who live on its shores. It is, however, stormy, probably due to the high hills by which it is surrounded.
Simon called Peter - The name “Peter” means a rock, and is the same as “Cephas.” See the Matthew 16:18 note; also John 1:42 note; 1 Corinthians 15:5 note.
