Charles Spurgeon Commentary Genesis 8:15-21

"And God spake unto Noah, saying, Go forth from the ark, thou, and thy wife, and thy sons, and thy sons` wives with thee. Bring forth with thee every living thing that is with thee of all flesh, both birds, and cattle, and every creeping thing that creepeth upon the earth; that they may breed abundantly in the earth, and be fruitful, and multiply upon the earth. And Noah went forth, and his sons, and his wife, and his sons` wives with him: every beast, every creeping thing, and every bird, whatsoever moveth upon the earth, after their families, went forth out of the ark. And Noah builded an altar unto Jehovah, and took of every clean beast, and of every clean bird, and offered burnt-offerings on the altar. And Jehovah smelled the sweet savor; and Jehovah said in his heart, I will not again curse the ground any more for man`s sake, for that the imagination of man`s heart is evil from his youth; neither will I again smite any more everything living, as I have done." — Genesis 8:15-21 (ASV)

And God spake unto Noah, saying, Go forth of the ark, thou, and thy wife, and thy sons, and thy sons' wives with thee. Bring forth with thee every living thing that is with thee, of all flesh, both of fowl, and of cattle, and of every creeping thing that creepeth upon the earth; that they may breed abundantly in the earth, and be fruitful, and multiply upon the earth. And Noah went forth, and his sons, and his wife, and his sons' wives with him: every beast, every creeping thing, and every fowl, and whatsoever creepeth upon the earth, after their kinds, went forth out of the ark. And Noah builded an altar unto the LORD, and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar. And the LORD smelled a sweet savour;

Until then, the earth had been repugnant to Jehovah. He had put it away from him as a foul thing, drowned beneath the flood; but after the offering of Noah's sacrifice, the Lord smelled a savour of rest.
