Bible Meaning: Sea of reeds
Strong's Concordance #H5488, #H3220, #G2063, #G2281
The word translated as "red" in the KJV Old Testament means reeds. The word for "sea" comes from the Hebrew that references this or other types of water bodies. In the New Testament, the phrase "Red Sea" is only used twice and is derived from the Greek words for the color and the sea.
Crossing the Sea
The Bible is unclear regarding the exact location where God permanently ended Egypt's pursuit of its Israelite slaves. Israel's crossing of the "Red Sea," during the Exodus, is almost certainly not referring to the large body of water we are familiar with today.
The Sinai Peninsula, on modern maps, has the Gulf of Suez as its western border and the Gulf of Aqaba as its eastern border. The sea is considered the body of water south of both Mount Sinai and the peninsula itself. It is too far away from Egypt and from where Israel encamped after leaving Pharaoh (Exodus 14:2, 9) to be the place where God performed one of his greatest miracles.
Israel's crossing either took place on the northernmost part of the Gulf of Suez or on one of the smaller bodies of water (lakes) between it and the Mediterranean. According to Holman's Bible Dictionary, evidence suggests the crossing took place near Lake Timsah that is north of the much larger Great Bitter Lake.
