If you look at this Parsha in a Sefer Torah, you will immediately notice that Bilaam’s narrative is written in “block form” without the usual open spaces (parsha “breaks”) that are found in most Parshiyot.
Bilam, the one-eyed man - whose vision proved to be myopic - sought in vain to cast an evil eye upon us. But he learned that we see things with 20-20 vision. We don't "cover the eye" of the land; we remove all the blinders from the world and reveal the truth of Hashem for all to see.
