For the commandments, “You shall not commit adultery,” “You shall not murder,” “You shall not steal,” “You shall not bear false witness,” “You shall not covet,” and if there is any other commandment, are all summed up in this saying, namely, “You shall love your neighbor as yourself.”
‘And you shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.’ This is the first commandment.
But take careful heed to do the commandment and the law which Moses the servant of the Lord commanded you, to love the Lord your God, to walk in all His ways, to keep His commandments, to hold fast to Him, and to serve Him with all your heart and with all your soul.
Then the Lord said to Moses, “Come up to Me on the mountain and be there; and I will give you tablets of stone, and the law and commandments which I have written, that you may teach them.”
Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches them, he shall be called great in the kingdom of heaven.
You have heard that it was said to those of old, ‘You shall not commit adultery.’ But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.
