DEUT475 We should cleave to Torah scholars. This verse commands us to cleave to Torah scholars in order that we should learn from the Torah's commandments from them. If someone is able to be together with a Torah scholar or is able to assist him and fails to do so, he has violated this commandment. Someone who remains in the company of Torah scholars will not be quick to sin. (Chinuch 434). The Rambam writes: It is the very nature of man to be influenced in opinion and action by his friends and colleagues and to behave like the people around him. Therefore, we must cleave to righteous people and sit near scholars in order to learn and be influenced by their actions. We must keep away from the wicked in order not to learn from their behavior. If you live in a place where people do not behave properly, you should move to a place where the inhabitants are righteous. If this is not possible, you should dwell alone. (Hilchos Daios 6:1). A man should try to marry the daughter of a Torah scholar. A parent should try to have his daughter marry a Torah scholar. We should eat and do business with Torah scholars. (ibid. 6:2)
