Charles Spurgeon Commentary Leviticus 25:1-2

"And Jehovah spake unto Moses in mount Sinai, saying, Speak unto the children of Israel, and say unto them, When ye come into the land which I give you, then shall the land keep a sabbath unto Jehovah." — Leviticus 25:1-2 (ASV)

The Jews had much rest provided for them. If they had had faith enough to obey God's commands, they might have been the most favored people; but they were not a spiritual people, and the Lord often had to lament their disobedience, as in the words recorded by Isaiah, O that thou hadst hearkened to my commandments! then had thy peace been as a river, and thy righteousness as the waves of the sea.
