Isaiah 40:27–31

Why sayest thou, O Jacob, and speakest, O Israel: My way is hid from the Lord, and my judgment is passed over from my God? 28Knowest thou not, or hast thou not heard? the Lord is the everlasting God, who hath created the ends of the earth: he shall not faint, nor labour, neither is there any searching out of his wisdom. 29It is he that giveth strength to the weary, and increaseth force and might to them that are not. 30You shall faint, and labour, and young men shall fall by infirmity. 31But they that hope in the Lord shall renew their strength, they shall take wings as eagles, they shall run and not be weary, they shall walk and not faint.
