Isaiah 40:28-30 Living Bible (TLB)
28 Don’t you yet understand? Don’t you know by now that the everlasting God, the Creator of the farthest parts of the earth, never grows faint or weary? No one can fathom the depths of his understanding. 29 He gives power to the tired and worn out, and strength to the weak. 30 Even the youths shall be exhausted, and the young men will all give up.
