Isaiah 26:2

The righteous nation - The converted Gentiles shall have the gates opened - a full entrance into all the glories and privileges of the Gospel; being fellow heirs with the converted Jews. The Jewish peculiarity is destroyed, for the middle wall of partition is broken down.

The truth - The Gospel itself - as the fulfillment of all the ancient types, shadows, and ceremonies; and therefore termed the truth, in opposition to all those shadowy rites and ceremonies. "The law was given by Moses; but grace and Truth came by Jesus Christ; "Joh 1:17, and see the note there.

Open ye the gates - This is probably the language of a chorus responding to the sentiment in Isaiah 26:1. The captive people are returning; and this cry is made that the gates of the city may be thrown open, and that they may be permitted to enter without obstruction (compare Psalm 24:7, Psalm 24:9; Psalm 118:19).

That the righteous nation which keepeth the truth - Who, during their long captivity and contact with pagan nations, have not apostatized from the true religion, but have adhered firmly to the worship of the true God. This was doubtless true of the great body of the captive Jews in Babylon.

26:2 The gates - Of the city, mentioned ver. 1 .The nation - The whole body of righteous men, whether Jews or Gentiles. For he seems to speak here, as he apparently did in the foregoing chapter, of the times of the gospel.Keepeth truth - Which is sincere in the true religion.
