Isaiah 40:28-30 NLT
Have you never heard?
Have you never understood?
The LORD is the everlasting God,
the Creator of all the earth.
He never grows weak or weary.
No one can measure the depths of his understanding.
He gives power to the weak
and strength to the powerless.
Even youths will become weak and tired,
and young men will fall in exhaustion.
NLT: New Living Translation
