Proverbs 4:23-25

Amplified Bible

²³ 
Watch over your heart with all diligence,
For from it flow the springs of life.
²⁴ 
Put away from you a deceitful (lying, misleading) mouth,
And put devious lips far from you.
²⁵ 
Let your eyes look directly ahead [toward the path of moral courage]
And let your gaze be fixed straight in front of you [toward the path of integrity].
