Family of Jacob, why do you say, "The LORD doesn't notice our condition"? People of Israel, why do you say, "Our God doesn't pay any attention to our rightful claims"?
Don't you know who made everything? Haven't you heard about him? The LORD is the God who lives forever. He created everything on earth. He won't become worn out or get tired. No one will ever know how great his understanding is.
He gives strength to those who are tired. He gives power to those who are weak.
Even young people become worn out and get tired. Even the best of them trip and fall.
But those who trust in the LORD will receive new strength. They will fly as high as eagles. They will run and not get tired. They will walk and not grow weak.
