🔼The name Parat in the Bible
Parat is the fourth of four rivers in Eden (the others being Pishon, Gihon, and Haddakel — Genesis 2:10-14). Even though most translations mention this river by its modern and New Testament name Euphrates (meaning Good Parat), the Old Testament consistently reads Parat.
🔼Etymology of the name Parat
The letters ת (taw) and ה (he) sometimes alternate, especially in cases of older names. These tend to be spelled with the letter taw while the word it came from evolved from being spelled with a taw to being spelled with a he. And so scholars think that the name Parat most likely comes from the verb פרה (para), bear fruit, be fruitful:

The name Parat means Fruitful. Neither NOBSE Study Bible Name List nor Jones' Dictionary of Old Testament Proper Names treats Parat, but for Euphrates (=eu-parat; the good parat), NOBSE reads That Which Makes Fruitful, and Jones reads Fruitfulness.
