The Quran

وَقالَ فِرعَونُ يا أَيُّهَا المَلَأُ ما عَلِمتُ لَكُم مِن إِلٰهٍ غَيري فَأَوقِد لي يا هامانُ عَلَى الطّينِ فَاجعَل لي صَرحًا لَعَلّي أَطَّلِعُ إِلىٰ إِلٰهِ موسىٰ وَإِنّي لَأَظُنُّهُ مِنَ الكاذِبينَ

Muhammad Asad

Whereupon Pharaoh said: "O you nobles! I did not know that you could have any deity other than myself!¹ Well, then, O Haman, kindle me a fire for [baking bricks of] clay, and then build me a lofty tower, that haply I may have a look at the god of Moses² - although, behold, I am convinced that he is of those who [always] tell lies!"

In view of the fact that the ancient Egyptians worshipped many gods, this observation is not to be taken literally; but since each of the Pharaohs was regarded as an incarnation of the divine principle as such, he claimed and received his people's adoration as their "Lord All-Highest" (cf. 79:24), combining within himself, as it were, all the qualities attributable to gods.
Or: "ascend to the god of Moses". Whichever of the two meanings is given to the verb ittali'u, Pharaoh's demand for a "lofty tower" is not only an allusion to the building of one of the great pyramids (see note 6 above), but also a derisory, contemptuous reference to Moses' concept of God as an all-embracing Power, inconceivably high above all that exists.
