The name Euphrates may have originated from Old Persian Ufratu, as it were from Avestan *hu-perethuua, meaning "good to cross over" (from hu-, meaning "good", and peretu, meaning "ford"). Alternatively, some suggest that the name Euphrates is possibly of Kurdish origin.
Euphrates in the Bible
The river Euphrates is one of the four rivers that flow from the Garden of Eden according to Genesis 2:13-15. It is the fourth river, after the Pishon, the Gihon, and the Tigris, to form from the river flowing out of the garden. The river also marked one of the boundaries of the land promised by God to Abraham and his descendants. In the Hebrew Bible, it is often referred to simply as "The River" (ha-nahar).
The word Euphrates is a translation for the word "Gush forth" or "break forth". It has always been assumed to mean "river" but this is not explicitly stated. It literally means "breaking forth of liquid". The river Euphrates was named from this root word, "To gush forth".
In the Book of Revelation, it is prophesied that in the "near future the Potamos Euphrates or "breaking forth like water" of the middle east will dry up in preparation for the Battle of Armageddon.
