Hear, O Israel, the Lord our God, the Lord is one.
Love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.” [So far, so good; this is Deuteronomy. 6:4–5.]
[And now Jesus adds a verse from Leviticus. 19:18.]
The second is this: “Love your neighbor as yourself.”
There is no commandment greater than these.
