-15: “My command is this: Love each other as I have loved you. Greater love has no one than this: to lay down one’s life for one’s friends. You are my friends if you do what I command. I no longer call you servants, because a servant does not know his master’s business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you.“

: “One who has unreliable friends soon comes to ruin,  but there is a friend who sticks closer than a brother.”

: “As iron sharpens iron, so one person sharpens another.”

-25: “Do not make friends with a hot-tempered person, do not associate with one easily angered, or you may learn their ways and get yourself ensnared.”

: “Do not be misled: “Bad company corrupts good character.”

: “Walk with the wise and become wise, for a companion of fools suffers harm.”
