Charity suffereth long

1 Corinthians 13.4:

Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up…

Charles Hodge:

Love suffereth long, i.e. is long-minded, or slow to be roused to resentment. It patiently bears with provocation, and is not quick to assert its rights or resent an injury.

It is kind, i.e. is inclined to perform good offices; is good-natured. The root of the verb means useful, and hence its primary sense is, disposed to be useful. The excellence here indicated is the positive side of that already mentioned. Love is not quick to resent evil, but is disposed to do good.

It envieth not. The word here used may express any wrong feeling excited in view of the good of others; not only envy, but hatred, emulation, and the like.

It vaunteth not itself, this includes all forms of the desire to gain the applause of others. Love does not seek to win admiration and applause.

Is not puffed up, i.e. conceited. This is the root of the preceeding. The man who has a high conceit of himself is apt to be boastful and desirous of praise. Love, on the other hand, is modest and humble; modest because humble.
