Psalm 20:4 May he give you the desire of your heart
I heard an interesting interpretation of this verse and I think it is a good one. Of course, we love it when God grants us the desires of our heart, but it's possible this verse means more than that. Perhaps it is a prayer for God to plant within our hearts God's desires for our lives so that His desires become our desires.
Psalm 20:7 Some trust in chariots and some in horses, but we trust in the name of the Lord our God.
