God will not hold you responsible for your thoughtless oaths. However, He will question you about your deliberate oaths. The expiation for breaking an oath is to feed ten needy people with food, typical of that which you feed to your own people, to clothe them or to set a slave free. One who cannot pay this, he must fast for three days to expiate his oaths. Keep your oaths. Thus, does God explain His Laws so that you will give Him thanks.
