Haftarat Yitro contains a selection that is part of Kedusha, an important part of liturgy, which is perhaps not appreciated enough. Another part of Kedusha is found in Yehezkel, and we compare the two, looking at the verses in their respective contexts.
Both prophets are describing majestic visions in which angels and the like play significant roles, but different aspects of the Divine Presence are manifest. Yeshayahu describes the earth as filled with God's presence, and Yehezkel, prophesying in exile, describing God's presence as being more concentrated somewhere else.
Yehezkel's message is that God did not abandon the Land of Israel, even during exile. Even though it seems like there is a big distance - as if God's presence is somewhere far above- He will yet eturn to dwell within us.
