Isaiah 40:1-2, 27-31 New Revised Standard Version (NRSV)
God’s People Are Comforted
40 Comfort, O comfort my people,
says your God.
2 Speak tenderly to Jerusalem,
and cry to her
that she has served her term,
that her penalty is paid,
that she has received from the Lord’s hand
double for all her sins.
[…]
27 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”?
28 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.
29 He gives power to the faint,
and strengthens the powerless.
30 Even youths will faint and be weary,
and the young will fall exhausted;
31 but those 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
