I prevented the dawning of the morning, and cried: I hoped in thy word.

Jamieson-Fausset-Brown Bible Commentary

147. prevented-literally, "came before," anticipated not only the dawn, but even the usual periods of the night; when the night watches, which might be expected to find me asleep, come, they find me awake (Ps 63:6; 77:4; La 2:19). Such is the earnestness of the desire and love for God's truth.

Matthew Henry's Concise Commentary

119:145-152 Supplications with the whole heart are presented only by those who desire God's salvation, and who love his commandments. Whither should the child go but to his father? Save me from my sins, my corruptions, my temptations, all the hinderances in my way, that I may keep thy testimonies. Christians who enjoy health, should not suffer the early hours of the morning to glide away unimproved. Hope in God's word encourages us to continue in prayer. It is better to take time from sleep, than not to find time for prayer. We have access to God at all hours; and if our first thoughts in the morning are of God, they will help to keep us in his fear all the day long. Make me lively and cheerful. God knows what we need and what is good for us, and will quicken us. If we are employed in God's service, we need not fear those who try to set themselves as far as they can out of the reach of the convictions and commands of his law. When trouble is near, God is near. He is never far to seek. All his commandments are truth. And God's promises will be performed. All that ever trusted in God have found him faithful.
