It is a compound of two words; Hosi is shortened into save; Anna a mere exclamation, complete. Blessed is He that cometh in the name of the Lord. The name of the Lord here is the name of God the Father; though we may understand it as His own name; inasmuch as He also is the Lord. But the former sense agrees better with the text above, I am come in My Father’s name. (5:43) He does not lose His divinity, when He teaches us humility.
