The prophet is comparing the greatness of God's presence to how impossible it is for man to build a place for God to rest on earth since the whole earth is nothing but a place for God to rest his feet.
God asks this question to show how useless man's efforts are to take care of God. AT: "You can not build a house adequate enough for me!" (See: [[rc://en/ta/man/translate/figs-rquestion]])
God asks this question to show man that he cannot provide God any rest. AT: "There is no place of rest good enough for me!" (See: [[rc://en/ta/man/translate/figs-rquestion]])
God asks this question to show that man did not create anything. AT: "My hand made all these things!" (See: [[rc://en/ta/man/translate/figs-rquestion]])
