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.

My zeal hath consumed me,.... Zeal for God and his glory, for his word and ordinances and worship; which is a fervour of the mind, burning love, and flaming affections for God, shown in a holy indignation against sin and sinners. This was a zeal according to knowledge, sincere and hearty, and what continued; and which was shown in embracing and defending the truths of the word, and resenting every indignity cast upon them; to such a degree, that it ate up his spirit, wore away his flesh, and almost consumed him; see Psa 69:9;

because mine enemies have forgotten thy words; not merely through an indifference to them, and inattention in hearing them; nor through want of an earnest heed to keep and retain them; nor through negligence in laying them up, and a carelessness in making use of proper means to recollect them; but through an aversion to them, an hatred of them, and a spiteful malicious contempt of them, casting them away and despising them; which stirred up the spirit of the psalmist, and raised such an emotion in him as was almost too much for him.
