When Jesus was asked for the greatest commandment, He gave two that cannot be separated: love God with all your heart, and love your neighbor as yourself. The neighbor, He showed, is whoever lies in your path needing mercy. These passages trace that second great commandment from the law of Moses through the parables of Jesus to the letters of the apostles.
30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. 31 And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.
37 This is the first and great commandment. 38 And the second is like unto it, Thou shalt love thy neighbour as thyself. 39 On these two commandments hang all the law and the prophets. 40 While the Pharisees were gathered together, Jesus asked them,
25 And, behold, a certain lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life? 26 He said unto him, What is written in the law? how readest thou? 27 And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself. 28 And he said unto him, Thou hast answered right: this do, and thou shalt live.
33 But a certain Samaritan, as he journeyed, came where he was: and when he saw him, he had compassion on him, 34 And went to him, and bound up his wounds, pouring in oil and wine, and set him on his own beast, and brought him to an inn, and took care of him. 35 And on the morrow when he departed, he took out two pence, and gave them to the host, and said unto him, Take care of him; and whatsoever thou spendest more, when I come again, I will repay thee. 36 Which now of these three, thinkest thou, was neighbour unto him that fell among the thieves? 37 And he said, He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise.
8 Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. 9 For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. 10 Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.
20 If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen? 21 And this commandment have we from him, That he who loveth God love his brother also.
28 Say not unto thy neighbour, Go, and come again, and to morrow I will give; when thou hast it by thee. 29 Devise not evil against thy neighbour, seeing he dwelleth securely by thee. Devise...: or, Practise no evil
