Matthew Henry Commentary Genesis 2:1-3

"And the heavens and the earth were finished, and all the host of them. And on the seventh day God finished his work which he had made; and he rested on the seventh day from all his work which he had made. 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 2:1-3 (ASV)

After six days, God ceased from all works of creation. In miracles, He has overruled nature, but never changed its settled course or added to it. God did not rest as one weary, but as one well pleased.

Notice the beginning of the kingdom of grace, in the sanctification, or keeping holy, of the Sabbath day. The solemn observance of one day in seven as a day of holy rest and holy work, to God's honor, is the duty of all to whom God has made known His holy Sabbaths.

At this time, none of the human race existed except our first parents. For them the Sabbath was appointed; and clearly for all succeeding generations also. The Christian Sabbath, which we observe, is a seventh day, and in it we celebrate the rest of God the Son and the finishing of the work of our redemption.
