Gill's Exposition of the Entire BibleMake thy face to shine upon thy servant,.... That is, lift up the light of thy countenance on me; favour me with thy gracious presence, and communion with thyself; manifest thyself unto me, and shed abroad thy love in my heart; cause the sun of righteousness to arise upon me, and commune with me, from above thy mercy seat; restore to me the joys of thy salvation, and let me have the comforts of thy good Spirit: this prayer is a part of the blessing of the high priest, Numbers 6:25; and teach me thy statutes; the more communion a man has with God, the more desirous he is of learning and doing his will.

Matthew Henry's Concise Commentary119:129-136 The wonders of redeeming love will fix the heart in adoration of them. The Scriptures show us what we were, what we are, and what we shall be. They show us the mercy and the justice of the Lord, the joys of heaven, and the pains of hell. Thus they give to the simple, in a few days, understanding of those matters, which philosophers for ages sought in vain. The believer, wearied with the cares of life and his conflicts with sin, pants for the consolations conveyed to him by means of the sacred word. And every one may pray, Look thou upon me, and be merciful unto me as thou usest to do unto those that love thy name. We must beg that the Holy Spirit would order our steps. The dominion of sin is to be dreaded and prayed against by every one. The oppression of men is often more than flesh and blood can bear; and He who knoweth our frame, will not refuse to remove it in answer to the prayers of his people. Whatever obscurity may appear as to the faith of the Old Testament believers, their confidence at the throne of grace can only be explained by their having obtained more distinct views of gospel privileges, through the sacrifices and services of their law, than is generally imagined. Go to the same place, plead the name and merits of Jesus, and you will not, you cannot plead in vain. Commonly, where there is a gracious heart, there is a weeping eye. Accept, O Lord, the tears our blessed Redeemer shed in the days of his flesh, for us who should weep for our brethren or ourselves.
Matthew Henry's Whole Bible CommentaryVerse 135 David here, as often as elsewhere, writes himself God's servant, a title he gloried in, though he was a king; now here, as became a good servant, 1. He is very ambitious of his Master's favour, accounting that his happiness and chief good. He asks not for corn and wine, for silver and gold, but, "Make thy face to shine upon thy servant; let me be accepted of thee, and let me know that I am so. Comfort me with the light of thy countenance in every cloudy and dark day. If the world frown upon me, yet do thou smile." 2. He is very solicitous about his Master's work, accounting that his business and chief concern. This he would be instructed in, that he might do it, and do it well, so as to be accepted in the doing of it: Teach me thy statutes. Note, We must pray as earnestly for grace as for comfort. If God hides his face from us, it is because we have been careless in keeping his statutes; and therefore, that we may be qualified for the returns of his favour, we must pray for wisdom to do our duty. |
