He - The man whom he had seen upon the throne. Them - Those whom God hath appointed to destroy the city: perhaps angels. Every man - Every one; 'tis an Hebrew idiom. Each of these had a weapon proper for that kind of destruction which he was to effect; and so, some to slay with the sword, another with the pestilence, another with famine. In his hand - Denoting both expedition in, and strength for the work.

Eze 20:41

I will be sanctified in you, etc. God is sanctified when he is manifested and recognized as holy (Le Eze 10:3; Num 20:13). That recognition would be the consequence of the restoration of Israel, for then it would be seen, even by the heathen, that the God of Israel had been holy and just and true in his judgments, and that he seeks to make men partakers of his holiness.
