Mark 12:28-31 New King James Version (NKJV)
The Scribes: Which Is the First Commandment of All?
29 Jesus answered him, “The [c]first of all the commandments is: ‘Hear, O Israel, the Lord our God, the Lord is one. 30 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.’ [d]This is the first commandment. 31 And the second, like it, is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.”
Mark 12:28-31 New International Version (NIV)
The Greatest Commandment
28 One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him, “Of all the commandments, which is the most important?”
29 “The most important one,” answered Jesus, “is this: ‘Hear, O Israel: The Lord our God, the Lord is one.[a] 30 Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’[b] 31 The second is this: ‘Love your neighbor as yourself.’[c] There is no commandment greater than these.”
