John Gill Bible Commentary

This is the day which the Lord hath made,.... Famous and remarkable for the above events. Meaning either the day of Christ's entrance into Jerusalem, in order to be delivered up to the Jews, and suffer and die in the place of his people; to which the following words agree: or the day of his resurrection (g) from the dead; when God gave him glory, and was matter of joy to those for whose justification he rose; or the Lord's day, kept in commemoration of it: or rather the whole Gospel dispensation, made a bright day by the sun of righteousness; and which is the now present day of salvation; we will rejoice and be glad in it; because of the blessings of grace, peace, pardon, righteousness, and salvation, which came through the humiliation and exaltation of Christ, and are published in the everlasting Gospel. The Targum is, "this day the Lord hath made, said the builders; let us rejoice and be glad in it, said the sons of Jesse.'' (g) So Suidas in voce which he observes fell on March 25.
