Iron is sharpened by iron: so doth a man sharpen himself on the countenance of his friend.
A friend loveth at all times, and as a brother is he born for the time of distress.
Thou shalt not hate thy brother in thy heart: thou shalt indeed rebuke thy neighbor, and not bear sin on account of him.
Thy own friend, and thy fathers friend, thou must not forsake; but into thy brothers house enter not on the day of thy calamity: better is a near neighbor than a distant brother.
A mans many companions are hurtful to him; but there is many a friend that cleaveth closer than a brother.
