Sirach 18:20LXX

18A fool will upbraid bitterly: and a gift of one ill taught consumeth the eyes.

19Before judgment prepare thee justice, and learn before thou speak.

20Before sickness take a medicine, and before judgment examine thyself, and thou shalt find mercy in the sight of God.

21Humble thyself before thou art sick, and in the time of sickness shew thy conversation.

22Let nothing hinder thee from praying always, and be not afraid to be justified even to death: for the reward of God continueth for ever.
