'Tower' in the Bible

therefore, behold, I am against you, and against your rivers, and I will make the land of Egypt an utter waste and desolation, from the tower of Seveneh even to the border of Ethiopia.

Thus says Yahweh: They also who uphold Egypt shall fall; and the pride of her power shall come down: from the tower of Seveneh shall they fall in it by the sword, says the Lord Yahweh.
