From the New City Catechism – #11 (Bold answer for children)
What does God require in the sixth, seventh, and eighth commandments?
Sixth, that we do not hurt, or hate, or be hostile to our neighbor, but be patient and peaceful, pursuing even our enemies with love. Seventh, that we abstain from sexual immorality and live purely and faithfully, whether in marriage or in single life, avoiding all impure actions, looks, words, thoughts, or desires, and whatever might lead to them. Eighth, that we do not take without permission that which belongs to someone else, nor withhold any good from someone we might benefit
