What is the question?
Radak: It is as if the gates ask, who is Melech ha'Kavod 1 [Malbim - for Whom we should rise amidst fear]?
Shabbos 30a: The gates thought that Shlomo calls himself Melech ha'Kavod, so they sought to swallow him. They asked him to clarify his words.
Why is He called "Hashem Izuz v'Gibor Hashem Gibor Milchamah"
Radak: The Aron would go to war with them, and due to it they defeated their enemies.
Malbim: Gibor is intrinsic strength - He demolishes all natural laws and subdues all of them with His miraculous, wondrous strength. Gibor Milchamah knows war strategies. He arranges all legions of nature according to His desire and Chachmah to fight, defeat and rule strongly - "Hashem k'Gibor Yetzei k'Ish Milchamos Ya'ir Kin'ah" (Yeshayah 42:13).
