Leupold Genesis part 38 verse 8

8. And God called the firmament heavens; and came evening, and came morning--second day.

Again, the giving of the name to the object just created is more than an outward thing. What the term "heavens" implies, that is what the new arrangement will serve to be for man. All this, especially the term "heavens," gives us warrant for describing this creative work as we did in connection with v. 6.

Our rendering, as in v. 5, "then came evening" is not as exact from one point of view as it might be. Wayhi is not the verb "come," but is from hayah, "to be," or even better "to become." This latter idea to show the progression of time we felt could well be marked by the English idiom, "then came evening," etc. The word for "evening," 'erebh, is commonly derived from the corresponding Hebrew root whose Arabic parallel means "to enter," "to go in." So, apparently, a poetic thought is involved in that the sun is thought of as going into its chamber, a thought found also in Ps. 19:5.

After "one" the ordinals are used, "day the second" (K. S. 315 n).

There follows in v. 9-13 the double work of the third day.
