1311a. The belly of N. is like that of Nut,(the sky)
1311b. when he ascends and lifts himself [to the sky].
130d. N. compasses the sky like Rē‘; N. traverses the sky like Thot.

N. has taken his stand with him in the north of the sky
2013a. Thou art a god who supports the sky
...And this is just the word "sky". Imagine how many more references to giants can be found
if you search words like "high", "tall", etc.
