Though an host. — Literally, Though a camp should encamp.
In this. — Either in this circumstance or in spite of this. (Comp. Psalms 78:32.) The LXX. ἐν ταύτῃ, followed by μίαν in the next clause, seems to refer it to the hope about to be expressed. The Rabbinical commentators (e.g., Aben Ezra and Rashi) refer back to the beginning of the psalm. “In this” — viz., that Jehovah is my light — “do I trust.” Rosenmiiller refers it to “the battle” just mentioned, in ipsa pugna.
