John Gill Bible Commentary

This gate of the Lord, into which the righteous shall enter. This seems to be spoken by some other person or persons, distinct from David and the Messiah, pointing at some particular and principal gate, upon hearing the above word: by which is meant, not the gate of the house of the sanctuary of the Lord, as the Targum; but the Messiah himself, afterwards spoken of as the stone rejected by the builders, and made the head of the corner; who is the way of access to God; the door into the church or sheepfold; the strait gate that leads to eternal life; by which none but righteous persons enter into heaven; even such who are made righteous, through the imputation of his righteousness to them; see Joh 10:1. . Psalms 118:21 psa 118:21 psa 118:21 psa 118:21I will praise thee, for thou hast heard me,.... Here the psalmist reassumes his part in this song, and determines to praise the Lord for hearing him when in distress, and when he was encompassed with his enemies, and for delivering him out of their hands; and art become my salvation; the author of it, and therefore deserving of praise; and who is no other than the Messiah Jesus, who is described in the next verse.
