What is the promise of the Lord to those who fear him?

“He holds success in store for the upright, he is a shield to those whose walk is blameless. Every word of God is flawless; he is a shield to those who take refuge in him. The sun will no more be your light by day, nor will the brightness of the moon shine on you, for the Lord will be your everlasting light, and your God will be your glory. But for you who revere my name, the sun of righteousness will rise with healing in its rays and you will go out and frolic like well-fed calves.”
