Proverbs 27:5-6, 9, 17

It’s better to be corrected openly if it stems from hidden love. You can trust a friend who wounds you with his honesty, but your enemy’s pretended flattery comes from insincerity.

Sweet friendships refresh the soul and awaken our hearts with joy, for good friends are like the anointing oil that yields the fragrant incense of God’s presence.

It takes a grinding wheel to sharpen a blade, and so one person sharpens the character of another.
