AND HE it is who has given freedom of movement to the two great bodies of water –* the one sweet and thirst-allaying, and the other salty and bitter - and yet has wrought between them a barrier and a forbidding ban.*

[Easy is it for Him to create likeness and variety:]* thus, the two great bodies of water [on earth] are not alike* the one sweet, thirst-allaying, pleasant to drink, and the other salty and bitter: and yet, from either of them do you eat fresh meat, and [from either] you take gems which you may wear; and on either thou canst see ships ploughing through the waves, so that you might [be able to] go forth in quest of some of His bounty, and thus have cause to be grateful.

[It comes down sweet - but] were it Our will, We could make it burningly salty and bitter: why, then, do you not give thanks [unto Us]?
