This is the day which Jehovah made He now speaks of that as a happy and pleasant day, on which he was at last established king over Israel, and the anointing of him by Samuel ratified by this event. Doubtless, all days were created alike by God, nevertheless David, by way of eminence, calls that the day of God which, after a long period of darkness, had dawned for the weal of the Church, because it was signalized by a notable event, deserving of being remembered by succeeding generations; and because the Church had thus emerged from a state of deep obscurity, he exhorts the faithful to mirth and joy, and that, too, by reason of the ignorance which many still displayed of the grace of God, or of their treating it with contempt, and of others being so lettered by their perverse attachment to Saul, that they could scarcely be brought to yield allegiance to David.

This is the day which the Lord hath made - As if it were a new day, made for this very occasion; a day which the writer of the psalm did not expect to see, and which seemed therefore to have been created out of the ordinary course, and added to the other days. He was in danger of death; his days were likely to be cut off and ended, so that he should see no more. But God had spared him, and added this joyous day to his life; and it was meet that for this he should be praised. It was so full of joy, so unexpected, so bright, so cheerful, that it appeared to be a new day coming fresh from the hand of the Almighty, unlike the other days of the year. So the Sabbath - the day that commemorates the resurrection of the Redeemer - is God's day. He claims it. He seems to have made it anew for man. Amidst the other days of the week - in a world where the ordinary days are filled up with so much of earth, so much toil, trouble, care, vexation, vanity, wickedness - it seems like one of the days that God made when he first made the world; before sin and sorrow entered; when all was calm, serene, happy. The Sabbath is so calm, so bright, so cheerful, so benign in its influence; it is so full of pleasant and holy associations and reminiscences, that it seems to be a day fresh from the hand of God, unlike the other days of the week, and made especially, as if by a new act of creation, for the good of mankind. So when a man is raised up from sickness - from the borders of the grave - it seems to be a new life given to him. Each day, week, month, year that he may live, is so much added to his life, as if it were created anew for this very purpose. He should, therefore, regard it not as his own, but as so much given to him by the special mercy and providence of God - as if added on to his life. Compare Isaiah 38:5.
We will rejoice and be glad in it - The psalmist, and all who united with him in his thanksgivings. So the Christian Sabbath. It is a day of joy - all joy, and no sorrow. It is a day to be happy in; a day of rest; a day, when the cares and toils of life are suspended; a day, when we are no longer harassed with those things which vex us in the worldliness of the week; a day, when we think of God, of redemption, of hope, of heaven. The Sabbath should be a day of joy, and not of gloom; it would be the happiest of all days to weary and jaded people everywhere, if they observed it aright. In a world of toil and sorrow, it is among the richest of God's blessings to people; it strengthens, refreshes, and cheers the heart of burdened and sorrowful man here; it lifts the soul to joyous contemplation of that eternal Sabbath where wearisome toll and sorrow shall be no more.

This is the day which the Lord hath made - As the Lord hath called me to triumph, this is the day which he hath appointed for that purpose. This is a gracious opportunity; I will improve it to his glory.

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.

This is the day--or period distinguished by God's favor of all others.
