satisfieth thy mouth with good things] Ps. 36. 8. and 146. 7. so that thy youth is renewed like the agles] As the eagle is renued in strength by sucking blood when she cannot feed, as some say, or, by casting her feathers, as others say: so God miraculously giveth strength to his people, above all mans expectation: or, he makes thee vigorous, as in thy youth, and active, like an eagle, Isaiah 40:31.
