Genesis 8:8-9

He sent forth a dove... — From the nature of its food, the raven had not brought back to Noah any special information; but as the dove feeds on vegetable products, he hopes that he shall learn by her means what is the state of “the ground,” the low-lying adâmâh. But as this species of bird does not fly far from its home, except when assembled in vast numbers, it quickly returned, finding water all around. This proves that the ark had not settled upon a lofty eminence; for as it had been already aground 120 days, and as within another fortnight the waters had “abated from off the earth,” it could only have been in some valley or plain among the mountains of Ararat that the waters were thus “on the face of the whole earth,” the larger word, yet which certainly does not mean here the whole world, but only a very small region in the immediate neighbourhood of the ark. For, supposing that the raven was sent out one week before the dove, forty-seven days (see Genesis 8:6) would have elapsed since Noah beheld the glorious panorama of mountain heights all around, and seven days afterwards the dove brought him a freshplucked olive-leaf. Yet, literally, the words are, for waters were upon the face of the whole earth. Plainly these large terms in the language of the Bible are to be limited in their interpretation by the general tenor of its narratives. For a similar conclusive instance, comp. Exodus 9:6 with Exodus 9:19.
