Pay all your debts, except the debt of love for others. You can never finish paying that! If you love your neighbor, you will fulfill all the requirements of God's law.
For the commandments against adultery and murder and stealing and coveting -- and any other commandment -- are all summed up in this one commandment: "Love your neighbor as yourself."
References for Romans 13:9
Love does no wrong to anyone, so love satisfies all of God's requirements.
