Deuteronomy 28 47
Because thou servedst not the LORD thy God with joyfulness, and with gladness of heart, for the abundance of all things
There, in the presence of the LORD your God, you and your households shall eat and rejoice in all you do, because the LORD your God has blessed you. Nevertheless, they will become his servants, so that they may learn the difference between serving Me and serving the kings of other lands.
For even while they were in their kingdom, with the abundant goodness that You had given them, and in the spacious and fertile land that You had set before them, they would not serve You or turn from their wicked ways.
They captured fortified cities and fertile land and took houses full of all goods, wells already dug, vineyards, olive groves, and fruit trees in abundance. So they ate and were filled; they grew fat and delighted in Your great goodness.
Serve the LORD with gladness; come into His presence with joyful songs.
