Gênesis 2:14

Of the “Hiddekel” and “Euphrates” there is no doubt: the former is the Tigris, or Tigres, which is a mere Graecising of its Oriental name, Daglath in Arabic, and Deklath in Syriac, and in the Targum of Onkelos. The word Hiddekel is startling as being a quadriliteral, but the Samaritan Codex reads the Dehel, that is, it has the article instead of the Hebrew Kheth. Mr. Sayce accepts the uncertain reading Hiddekel, and says (Chald. Gen., p. 84) that Hid is the Accadian name for river. Dekel, Tigris, is said to mean an arrow. The Samaritan reading is probably right.

Euphrates. — No description is given of this as being the largest and best known of Asiatic rivers. Hence, probably, the Pison and Gihon were but small streams. Euphrates is the Greek manner of pronouncing the Hebrew Phrath, the first syllable being simply a help in sounding the double consonant. In Accadian it is called Purrat, and means “the curving water,” being so named from its shape.
