Proverbs 27 - ESV

Do not forsake your friend and your father's friend,
and do not go to your brother's house in the day of your calamity.
Better is a neighbor who is near
than a brother who is far away.

The prudent sees danger and hides himself,
but the simple go on and suffer for it.

Iron sharpens iron,
and one man sharpens another.

As in water face reflects face,
so the heart of man reflects the man.
