Tobit 12:10

10 but those who commit sin are the enemies of their own lives.

Tobit 12:10 In-Context

8 Prayer is good when accompanied by fasting, almsgiving, and righteousness. A little with righteousness is better than much with wrongdoing. It is better to give alms than to treasure up gold.
9 For almsgiving delivers from death, and it will purge away every sin. Those who perform deeds of charity and of righteousness will have fulness of life;
10 but those who commit sin are the enemies of their own lives.
11 "I will not conceal anything from you. I have said, `It is good to guard the secret of a king, but gloriously to reveal the works of God.'
12 And so, when you and your daughter-in-law Sarah prayed, I brought a reminder of your prayer before the Holy One; and when you buried the dead, I was likewise present with you.
