"Above all else guard your heart,
for it is the wellspring of life.
Put away perversity from your mouth;
keep corrupt talk far from your lips.
Let your eyes look straight ahead,
fix your gaze directly before you.
Make level paths for your feet
and take only ways that are firm.
Do not swerve to the right or the left;
keep your foot from evil."
Proverbs 4: 23-27, NIV
