The Lord tells Moses to speak to the whole congregation: be holy, for he is holy. They must respect mother and father, keep the Sabbaths, not turn to idols and offer the peace offering in a way that will be accepted. When they reap, they must not harvest to the edges of the field or glean the vineyard but leave it for the poor and the foreigner.
A series of rules for living together follows: do not steal, lie or deceive, do not swear falsely by his name, do not oppress or withhold the hired worker's wages, do not curse the deaf or put a stumbling block before the blind. In the courts there will be no injustice, no partiality to the poor or deference to the great. Do not go about slandering, do not endanger a neighbor's life, do not hate in your heart but rebuke frankly, do not take vengeance or bear a grudge, and love your neighbor as yourself.
Mixtures in livestock, fields and clothing are also forbidden, along with divination and consulting mediums, and certain mourning practices such as cuts or tattoos. They are told to rise before the gray head, honor the elderly, love the foreigner as one of their own and use honest scales and measures. The chapter ends by recalling that the Lord brought them out of Egypt.
