The commandments, “You shall not commit adultery; You shall not murder; You shall not steal; You shall not covet”; and any other commandment, are summed up in this word, “Love your neighbor as yourself.”
Take good care to observe the commandment and instruction that Moses the servant of the Lord commanded you, to love the Lord your God, to walk in all his ways, to keep his commandments, and to hold fast to him, and to serve him with all your heart and with all your soul.
The Lord said to Moses, “Come up to me on the mountain, and wait there; and I will give you the tablets of stone, with the law and the commandment, which I have written for their instruction.”
Therefore, whoever breaks one of the least of these commandments, and teaches others to do the same, will be called least in the kingdom of heaven; but whoever does them and teaches them will be called great in the kingdom of heaven.
You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lust has already committed adultery with her in his heart.
