Psalms 117 - Introduction
INTRODUCTION TO PSALM 117
The inscription of this psalm in the Syriac version is,
"it is said concerning those of the house (or the companions) of Ananias, when they came out of the furnace; likewise it foretells the calling of the Gentiles by the declaration of the Gospel.''
Which last is right; for the apostle has quoted it, to prove the Gentiles should glorify God for his mercy, Romans 15:9. Aben Ezra thinks it concerns only the nations subdued by David; but he quotes R. Moseh, as of opinion that all nations are comprehended: and Kimchi affirms that the psalm belongs to the times of the Messiah; and supposes there is a mystery in its consisting of two verses only; and that it intimates that in those times there will be two people that will serve the Lord; Israel, with the law; and the Gentiles, with the seven precepts of Noah. It certainly refers to Gospel times, and to the conversion of the Gentiles; and when Jews and Gentiles should make one people, and be partakers of the same privileges and blessings; receive the same doctrines, submit to the same ordinances, and be under the same law, to Christ their King.
