why do they call it the sea of galilee
Sea of Galilee In the New Testament the term "sea of Galilee" (Greek: θάλασσαν τῆς Γαλιλαίας, thalassan tēs Galilaias) is used in the gospel of Matthew 4:18; 15:29, the gospel of Mark 1:16; 7:31, and in the gospel of John 6:1 as "the sea of Galilee, which is the sea of Tiberias" (θαλάσσης τῆς Γαλιλαίας τῆς Τιβεριάδος, thalassēs tēs Galilaias tēs Tiberiados), the late 1st century CE name.[10] Sea of Tiberias is also the name mentioned in Roman texts and in the Jerusalem Talmud, and was adopted into Arabic as  Buhairet Tabariyya (help·info) (بحيرة طبريا), "Lake Tiberias".
Red Sea Red Sea is a direct translation of the Greek Erythra Thalassa (Ερυθρὰ Θάλασσα), Latin Mare Rubrum (alternatively Sinus Arabicus, literally "Arabian Gulf"), Arabic: البحر الأحمر‎, translit. Al-Baḥr Al-Aḥmar (alternatively بحر القلزم Baḥr Al-Qulzum, literally "the Sea of Clysma"), Somali Badda Cas and Tigrinya Qeyyiḥ bāḥrī (ቀይሕ ባሕሪ). The name of the sea may signify the seasonal blooms of the red-coloured Trichodesmium erythraeum near the water's surface.[5] A theory favored by some modern scholars is that the name red is referring to the direction south, just as the Black Sea's name may refer to north. The basis of this theory is that some Asiatic languages used color words to refer to the cardinal directions.[6] Herodotus on one occasion uses Red Sea and Southern Sea interchangeably.[7]
