Matthew Henry on Leviticus 25:1-7

All labour was to cease in the seventh year, as much as daily labour on the seventh day. These statues tell us to beware of covetousness, for a man's life consists not in the abundance of his possessions. We are to exercise willing dependence on God's providence for our support; to consider ourselves the Lord's tenants or stewards, and to use our possessions accordingly. This year of rest typified the spiritual rest which all believers enter into through Christ. Through Him we are eased of the burden of wordly care and labour, both being sanctified and sweetened to us; and we are enabled and encouraged to live by faith.
