A farmer understands that the earth also needs rest. This natural understanding of the farmer is seen here as a divine law that benefits the land, animals, and people. Especially, the poor and those who have lost their property can eat the fruits that the earth produces freely during this year. However, there is a rule for them: they should take only what is necessary and leave the rest for wild animals. Verse 12 emphasizes the need for a Sabbath rest with a more humanitarian rather than religious meaning. The goal is to make sure that after a week of work, there is a day of rest for both animals and humans. To introduce the upcoming festive calendar, the Israelites are warned not to call upon the names of foreign gods. Remember, calling on a name was, for the ancient people of the East, like accepting the person. So, by calling upon the name of a god, they acknowledged and accepted that deity. The prophets condemned this as idolatry but also saw it as adultery or a breach of fidelity owed to the Lord (cf. Hos 2:17; Zech 13:2).
