Charles H. Spurgeon on Psalms 119:147

I prevented the dawning of the morning, and cried. He was up before the sun, and began his pleadings before the dew began to leave the grass. Whatever is worth doing is worth doing speedily. This is the third time that he mentions that he cried. He cried, and cried, and cried again. His supplications had become so frequent, fervent, and intense, that he might hardly be said to be doing anything else from morning to night but crying unto his God. So strong was his desire after salvation that he could not rest in his bed; so eagerly did he seek it that at the first possible moment he was on his knees.

I hoped in thy word. Hope is a very powerful means of strengthening us in prayer. Who would pray if he had no hope that God would hear him? Who would not pray when he has a good hope of a blessed issue to his entreaties? His hope was fixed upon God's word, and this is a sure anchorage, because God is true, and in no case has he ever run back from his promise, or altered the thing that has gone forth from his mouth. He who is diligent in prayer will never be destitute of hope. Observe that as the early bird gets the worm, so the early prayer is soon refreshed with hope.
