Isaiah 40:29-31

MSTC(i) 29 But that he giveth strength unto the weary, and power unto the faint? 30 Children are weary and faint, and the strongest men fall: 31 But unto them that have the LORD before their eyes, shall strength be increased, Eagles wings shall grow upon them; When they run, they shall not fall; and when they go, they shall not be weary."
