Isaiah 40:11-12;29-31  KJV

¹¹ He shall feed his flock like a shepherd: he shall gather the lambs with his arm, and carry them in his bosom, and shall gently lead those that are with young.

¹² Who hath measured the waters in the hollow of his hand, and meted out heaven with the span, and comprehended the dust of the earth in a measure, and weighed the mountains in scales, and the hills in a balance?

²⁹ He giveth power to the faint; and to them that have no might he increaseth strength.

³⁰ Even the youths shall faint and be weary, and the young men shall utterly fall:

³¹ But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.
