before sending it out the second time, and the same again before sending it the third time (Gen 8:10 and Gen 8:12). The dove, when first sent out, “ found no rest for the sole of its foot;” for a dove will only settle upon such places and objects as are dry and clean. It returned to the ark and let Noah take it in again (Gen 8:8, Gen 8:9). The second time it returned in the evening, having remained out longer than before, and brought a fresh (טרף freshly plucked) olive-leaf in its mouth. Noah perceived from this that the water must be almost gone, had “abated from off the earth,” though the ground might not be perfectly dry, as the olive-tree will put out leaves even under water. The fresh olive-leaf was the first sign of the resurrection of the earth to new life after the flood, and the dove with the olive-leaf a herald of salvation. The third time it did not return; a sign that the waters had completely receded from the earth. The fact that Noah waited 40 days before sending the raven, and after that always left an interval of seven days, is not to be accounted for on the supposition that these numbers were already regarded as significant. The 40 days correspond to the 40 days during which the rain fell and the waters rose; and Noah might assume that they would require the same time to recede as to rise. The seven days constituted the week established at the creation, and God had already conformed to it in arranging their entrance into the ark (Gen 7:4, Gen 7:10). The selection which Noah made of the birds may also be explained quite simply from the difference in their nature, with which Noah must have been acquainted; that is to say, from the fact that the raven in seeking its food settles upon every carcase that it sees, whereas the dove will only settle upon what is dry and clean.
verses 13-19
Noah waited some time, and then, on the first day of the first month, in the 601st year of his life, removed the covering from the ark, that he might obtain a freer prospect over the earth. He could see that the surface of the earth was dry; but it was not till the 27th day of the second month, 57 days, therefore, after the removal of the roof, that the earth was completely dried up. Then God commanded him to leave the ark with his family and all the animals; and so far as the latter were concerned, He renewed the blessing of the creation (Gen 8:17 cf. Gen 1:22). As the flood commenced on the 17th of the second month of the 600th year of Noah's life, and ended on the 27th of the
