A few scriptures that come to mind that deal with this very topic are:
Luke 6:31
And as ye would that men should do to you, do ye also to them likewise.
Proverbs 18:24a
A man that hath friends must shew himself friendly
Luke 6:31
And as ye would that men should do to you, do ye also to them likewise.
Proverbs 18:24a
A man that hath friends must shew himself friendly
Proverbs 27:5-10 KJV
5 Open rebuke is better than secret love. 6 Faithful are the wounds of a friend; but the kisses of an enemy are deceitful. 7 The full soul loatheth an honeycomb; but to the hungry soul every bitter thing is sweet. 8 As a bird that wandereth from her nest, so is a man that wandereth from his place. 9 Ointment and perfume rejoice the heart: so doth the sweetness of a man's friend by hearty counsel. 10 Thine own friend, and thy father's friend, forsake not; neither go into thy brother's house in the day of thy calamity: for better is a neighbour that is near than a brother far off.
