Deuteronomy 6:5

³⁰You 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.

³⁷Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’

²⁷He answered, “You shall love the Lord your God with all your heart, with all your soul, with all your strength, and with all your mind;and your neighbor as yourself.”

¹²Now, Israel, what does the LORD your God require of you, but to fear the LORD your God, to walk in all his ways, to love him, and to serve the LORD your God with all your heart and with all your soul,

⁶The LORD your God will circumcise your heart, and the heart of your offspring, to love the LORD your God with all your heart and with all your soul, that you may live.

²⁹But from there you shall seek the LORD your God, and you will find him when you search after him with all your heart and with all your soul.

³For this is loving God, that we keep his commandments. His commandments are not grievous.

³³and to love him with all the heart, with all the understanding, all the soul, and with all the strength, and to love his neighbor as himself, is more important than all whole burnt offerings and sacrifices.”

¹³It shall happen, if you shall listen diligently to my commandments which I command you today, to love the LORD your God, and to serve him with all your heart and with all your soul,

²⁰In that day you will know that I am in my Father, and you in me, and I in you. ²¹One who has my commandments and keeps them, that person is one who loves me. One who loves me will be loved by my Father, and I will love him, and will reveal myself to him.”
