New Testament

Matthew 22:40

34 Now when the Pharisees heard that he had silenced the Sadducees, they assembled together. 35 And one of them, an expert in religious law, asked him a question to test him: 36 “Teacher, which commandment in the law is the greatest?” 37 Jesus said to him, “‘Love the Lord your God with all your heart, with all your soul, and with all your mind.’ 38 This is the first and greatest commandment. 39 The second is like it: ‘Love your neighbor as yourself.’ 40 All the law and the prophets depend on these two commandments.

Mishnah

9 He [Rabban Yohanan] said unto them: go forth and observe which is the right way to which a man should cleave? Rabbi Eliezer said, a good eye; Rabbi Joshua said, a good companion; Rabbi Yose said, a good neighbor; Rabbi Shimon said, foresight. Rabbi Elazar said, a good heart. He [Rabban Yohanan] said to them: I prefer the words of Elazar ben Arach, for in his words your words are included. He [Rabban Yohanan] said unto them: go forth and observe which is the evil way which a man should shun? Rabbi Eliezer said, an evil eye; Rabbi Joshua said, an evil companion; Rabbi Yose said, an evil neighbor; Rabbi Shimon said, one who borrows and does not repay for he that borrows from man is as one who borrows from God, blessed be He, as it is said, “the wicked borrow and do not repay, but the righteous deal graciously and give” (Psalms 37:21). Rabbi Elazar said, an evil heart. He [Rabban Yohanan] said to them: I prefer the words of Elazar ben Arach, for in his words your words are included.
