| Geneva Study Bible God is the LORD, which hath shewed us {o} light: bind the sacrifice with cords, even unto the horns of the altar. (o) Because he has restored us from darkness to light, we will offer sacrifices and praises to him. Wesley's Notes 118:27 The Lord - Or, The mighty God, as this name of God signifies, and as he shewed himself to be by this, his wonderful work. Who - Who hath scattered our dark clouds, and put us into a state of peace, and safety, and happiness. The horns - These are supposed to he made for this very use, that the beasts should be bound and killed there. These three last verse s are David's words. Jamieson-Fausset-Brown Bible Commentary 27-29. showed us light-or favor (Ps 27:1; 97:11). With the sacrificial victim brought bound to the altar is united the more spiritual offering of praise (Ps 50:14, 23), expressed in the terms with which the Psalm opened. Matthew Henry's Concise Commentary 118:22,23, may refer to David's preferment; but principally to Christ. 1. His humiliation; he is the Stone which the builders refused: they would go on in their building without him. This proved the ruin of those who thus made light of him. Rejecters of Christ are rejected of God. 2. His exaltation; he is the chief Cornerstone in the foundation. He is the chief Top-stone, in whom the building is completed, who must, in all things, have the pre-eminence. Christ's name is Wonderful; and the redemption he wrought out is the most amazing of all God's wondrous works. We will rejoice and be glad in the Lord's day; not only that such a day is appointed, but in the occasion of it, Christ's becoming the Head. Sabbath days ought to be rejoicing days, then they are to us as the days of heaven. Let this Saviour be my Saviour, my Ruler. Let my soul prosper and be in health, in that peace and righteousness which his government brings. Let me have victory over the lusts that war against my soul; and let Divine grace subdue my heart. The duty which the Lord has made, brings light with it, true light. The duty this privilege calls for, is here set forth; the sacrifices we are to offer to God in gratitude for redeeming love, are ourselves; not to be slain upon the altar, but living sacrifices, to be bound to the altar; spiritual sacrifices of prayer and praise, in which our hearts must be engaged. The psalmist praises God, and calls upon all about him to give thanks to God for the glad tidings of great joy to all people, that there is a Redeemer, even Christ the Lord. In him the covenant of grace is made sure and everlasting. |
