In the Hebrew, it is much stronger than that. It says, Fervently do I yearn over You. Maybe that is a little too syrupy for those of us in this day and age. But that is what it says. Fervently do I yearn over You! And then comes a literal torrent of names of God. There are eight of them, right in a row.
David knew God's attributes as expressed by His names, and, thus, he conducted his life accordingly. He called upon the name of God. By faith, he trusted God to intervene in the affairs of men. He knew what God would do (i.e., what He could be trusted to do) by the way that God expressed Himself through His names.
I will put this into a very simple illustration. You are doing things like this virtually every day with other human beings. If your car breaks down, do you take it to the dentist? No, you take it to the person who has the name - auto mechanic. (Or, the person who has the reputation.) You call upon that person, when you are in need to repair your automobile. When your teeth need fixed, you do not go to the bank teller. You go to the person who has the name, the title, and the reputation of being able to take care of your teeth.
It is this same principle that is at work with God. By His names, He illustrates what He is skilled at doing, and not only skilled at doing, but what He will do. Sometimes the name will even describe the parameters of His blessing, or the conditions that are imposed upon receiving the fulfillment of that.
So that is what David was doing here, in his prayers. He was calling upon God, as God had revealed Himself by His names. And he would be confident - just as you would be confident in taking your automobile (or whatever it was) to the person who had the reputation of having the skill to be able to do that. You would call upon that person. That is what David did, and that is what you and I need to do. That is why you need to know the names of God. God is skilled, and God is willing to help. Through His names, He reveals what He is willing to do.
