Isaiah 40:28-29

International Children’s Bible

²⁸ Surely you know.
    Surely you have heard.
The Lord is the God who lives forever.
    He created all the world.
He does not become tired or need to rest.
    No one can understand how great his wisdom is.
²⁹ The Lord gives strength to those who are tired.
    He gives more power to those who are weak.
