My voice shall thou hear in the morning, O Lord,.... These words may be considered either as expressing the confidence of the psalmist, that the Lord would hear and answer him, and that in the morning, every morning, as soon and as often as he prayed; or that he would hear him early, quickly, speedily, seasonably, and at the best time; or else as declaring what he would do in consequence of his resolution to pray to the Lord in Ps 5:2; he would pray to him every morning: the morning is a proper time for prayer, both to return thanks to God for refreshing sleep and rest, for preservation from dangers by fire, by thieves and murderers, and for renewed mercies in the morning; as also to pray to God to keep from evil and dangers the day following; to give daily food, and to succeed in business and the employments of life; and for a continuation of every mercy, temporal and spiritual.
God should be served and sought in the first place; and so to do looks as if God was with his people, and they with him, when they awake in the morning. The Targum and Arabic version consider the words as a petition, and render them, "Hear in the morning, O Lord, my voice", or "my petition"; and so bear the same sense as the other petitions;in the morning will I direct [my prayer] unto thee; or "set [it] in order" : not so much respecting the order of words, the method of prayer, which is sometimes very broken and confused, and yet regarded by God; but in allusion either to the shewbread, placed in order on the table, which was typical of Christ's continual intercession for his people, Ex 40:4; or to the offering of incense and other sacrifices, which when offered were put in order upon the altar; and to which prayer is compared, Ps 141:2.
