243. _Gopher_ some make out to be pine, others hemlock, still others cedar; hence, a guess is rather difficult. The choice appears to have been made owing to its lightness or its resinous quality, so that it might float more easily upon the water and be impervious to it. 244. _Kinnim_ signifies "nests" or "chambers"; that is separate spaces for the various animals. Bears, sheep, deer and horses did not dwell in one and the same place, but the several species had their respective quarters. 245. But what is meant by _bitumen_, I do not know. With us vessels are made water tight with pitch and tow. Pitch, it is true, withstands water, but it also invites the flame. There is no bitumen with us which resists water, hence we raise no objection to "bitumen" being rendered "pitch." 246. You may ask: Why does God prescribe everything so accurately? The injunction to build the ark should have been sufficient. Reason could determine for itself the rules concerning dimensions and mode of construction. Why, then, does God give such careful instruction with reference to dimensions and materials? Certainly that Noah, after undertaking all things according to the Lord's direction (as Moses built the tabernacle according to the model received on the mount), should with the greater faith trust that he and his people were to be saved, nor entertain any doubt concerning a work ordered by the Lord himself, even how it should be made. This is the reason the Lord gives his directions with such attention to detail. V. 15. _And this is how thou shalt make it: the length of the ark three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits._ 247. A nice geometrical and mathematical exercise concerning the form and dimensions of the ark is here presented. The views of writers vary. Some claim it was four-cornered, others that it was gabled like nearly all our structures in Europe. As for myself, I hold it was four-cornered. Eastern people's were not acquainted with gabled buildings. Theirs were evidently of four-cornered form, as the Bible mentions people walking on roofs. Similar was the shape of the temple. 248. There is a difference of opinion also concerning the arrangement of the animals in their quarters, which occupied the upper, which the central and which the lower places, this being the distinction warranted by the text. No certainty, however, can be arrived at. It is likely that Noah himself and the birds occupied the upper part, the clean animals the central and the unclean animals the lower one. The rabbis assert the lower part served the purpose of storing dung. But I think the dung was thrown out of the window, for its removal was necessitated by such a multitude of beasts abiding in the ark for over a year.
