Proverbs 10:11 The mouth of a righteous man is a well of life: but violence covereth the mouth of the wicked.
12 Hatred stirreth up strifes: but love covereth all sins.
Jesus told the woman at the well if she drank of the water He could give her she would never thirst again. This means that as a righteous person we are a well of living water to share with others. Again we see that the wicked are violent people and leads to nothing but destruction. As verse 12 goes on to say that hatred causes all kinds sins and it can lead to all kinds of division. Then we see that love covers a multitude of sins and we see this appearing several times in new testament. 1 Peter 4:8 says And above all things have fervent charity among yourselves: for charity shall cover the multitude of sins. True love seeks the highest good for another.
