Isaiah 40:27-31

Why do you say, O Jacob,
    and speak, O Israel,
“My way is hidden from the Lord,
    and my right is disregarded by my God”?
Have you not known? Have you not heard?
The Lord is the everlasting God,
    the Creator of the ends of the earth.
He does not faint or grow weary;
    his understanding is unsearchable.
He gives power to the faint,
    and to him who has no might he increases strength.
Even youths shall faint and be weary,
    and young men shall fall exhausted;
but they who wait for the Lord shall renew their strength;
    they shall mount up with wings like eagles;
they shall run and not be weary;
    they shall walk and not faint.

Psalm 91:1-8

He who dwells in the shelter of the Most High
    will abide in the shadow of the Almighty.
I will say to the Lord, “My refuge and my fortress,
    my God, in whom I trust.”

For he will deliver you from the snare of the fowler
    and from the deadly pestilence.
He will cover you with his pinions,
    and under his wings you will find refuge;
    his faithfulness is a shield and buckler.
You will not fear the terror of the night,
    nor the arrow that flies by day,
nor the pestilence that stalks in darkness,
    nor the destruction that wastes at noonday.

A thousand may fall at your side,
    ten thousand at your right hand,
    but it will not come near you.
You will only look with your eyes
    and see the recompense of the wicked.

Psalm 121:7–8
“The Lord will keep you from all evil; He will keep your life. The Lord will keep your going out and your coming in from this time forth and forevermore.”
