Better alone than in bad company.
Associate with men of good judgment.
Bad company is the devil's net.
A wicked man will rob thee of precious time, if he doth no more
mischief.
A good companion makes good company.
A man is known by the company he keeps.
Birds of a feather flock together.
He who walks with wise men will be wise,
But the companion of fools will be destroyed.
Prov. 13:20
