Isaiah 40:30-31

40:30 Even youths get tired and weary;

even strong young men clumsily stumble.

40:31 But those who wait for the Lord’s help find renewed strength;

they rise up as if they had eagles’ wings,

they run without growing weary,

they walk without getting tired.

Isaiah 54:10

54:10 Even if the mountains are removed

and the hills displaced,

my devotion will not be removed from you,

nor will my covenant of friendship be displaced,”

says the Lord, the one who has compassion on you.
