Book of Enoch (1 Enoch) 77:7
And the remaining four come forth on the side of the north to their own sea, 〈two of them to〉 the Erythraean Sea, and two into the Great Sea and discharge themselves there [and some say: into the desert].
Background and history of Book of Enoch (1 Enoch), and issues with this book.
R. H. Charles, The Book of Enoch (London: SPCK, 1917), public domain. The verse text is the English Wikisource transcription of that translation. Charles’s editorial signs are kept. He rearranges some verses in chapters 5, 39, 90, 91, and 106, so those chapters are not a straight 1, 2, 3 sequence.
