Charles Ellicott Commentary Genesis 2:3

"And God blessed the seventh day, and hallowed it; because that in it he rested from all his work which God had created and made." — Genesis 2:3 (ASV)

Sanctified it: That is, separated it from ordinary uses and hallowed it. Legal observance of the Sabbath did not begin until the days of Moses (Exodus 31:13; Exodus 35:2); but this blessing and sanctification were given prior to any covenant with man, and by Elohim, the God of nature, and not Jehovah, the God of grace. The weekly rest, therefore, is universal, permanent, and independent of the Mosaic law.

Which God created and made: Literally, created to make. God created the world in order to make, form, and fashion it. There is a work of completion which follows creation, and this may still be going on, and be perfected only when there is a new heaven and a new earth.

THE GENERATIONS OF THE HEAVENS AND OF THE EARTH (Genesis 2:4 to Genesis 4:26).

After the hymn of creation, the rest of the Book of Genesis is divided into ten sections of very unequal length, called tôldôth, translated by the Septuagint as the Book of Genesis, or generation, from which the title given by St. Matthew to his Gospel is taken. (See note on Genesis 5:1.) This title, however, does not mean a genealogical list of a person’s ancestors, but the register of his posterity. As applied to the heavens and the earth, it signifies the history of what followed their creation.
