Proverbs 27:5-6, 9, 17

Open rebuke is better Than love carefully concealed. Faithful are the wounds of a friend, But the kisses of an enemy are deceitful.

Ointment and perfume delight the heart, And the sweetness of a man’s friend gives delight by hearty counsel.

As iron sharpens iron, So a man sharpens the countenance of his friend.
