He that learns from his fellow a single chapter or a single Halacha must pay him honour
Who knows, even if a small thing is said by his friend, he should be honored for it?
("He who learns from his fellow a single chapter or a single walk or a single verse or a single speech, even if they are one, must be treated with honor" - Avot 6:3, and so: "And he who learns from his fellow a single chapter or a single walk or a single verse or even if they are one, must be treated with honor, as we have seen in David, king of Israel, that he should not From Ahithophel, his master, his commander, and his advisor, said to him: "And you are a man according to my ways, my commander, and my advisor, and not words of light or weight." And what did David, king of Israel, say to Ahithophel? From Ahithophel, his master, his commander, and his advisor, said to him: "He is a man according to my ways, my commander, and my advisor, and not words of light or weight?" Or one step at a time, as much as is necessary to conduct oneself with honor, as it is said (Proverbs 3): "The honor of the wise will be theirs" - Elijah the Zuta (Man of Peace), Parshah 17)
