Genesis 2 - Matthew Henry's Concise Commentary on the Bible
The first sabbath.
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 observing of one day in seven as a day of holy rest and holy work, to God's honour, is the duty of all to whom God has made known his holy sabbaths. At this time none
of the human race were in being but 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 the work of our redemption. (Ge 2:4-7)
