One of the scribes came up and heard them disputing with one another, and seeing that he answered them well, asked him, "Which commandment is the first of all?"
Jesus answered, "The first is, `Hear, O Israel: The Lord our God, the Lord is one;
and you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength.'
The second is this, `You shall love your neighbor as yourself.' There is no other commandment greater than these."
