27Why do you say, O Jacob,
and speak, O Israel,
“My way is hidden from the Lord,
and my right is disregarded by my God”?
28Have 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.
29He gives power to the faint,
and to him who has no might he increases strength.
30Even youths shall faint and be weary,
and young men shall fall exhausted;
31but 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.
