God commanded ALL Israelites to let their land lie unplowed and unused every seventh year (Exodus 23:10-11). Because they were an agricultural society, this would mean that every seventh year would essentially be a welcomed break from work, a time of rest and refreshment.
God still intends for us to take breaks from our work to reconnect with him, with ourselves, and with others. Jesus told us that the first and greatest commandment is to "love the Lord your God with all your heart and with all your soul and with all your mind" (Matthew 33:37). And he said that the second is like it, to "love your neighbor as yourself" (Matthew 22:39).
