Put away from you crooked speech, and put devious talk far from you.
Let your eyes look directly forward, and your gaze be straight before you.
Ponder the path of your feet; then all your ways will be sure.
Do not swerve to the right or to the left; turn your foot away from evil. - Proverbs 4:24-27 (ESV)
My son, be attentive to my wisdom; incline your ear to my understanding, that you may keep discretion, and your lips may guard knowledge. - Proverbs 5:1 (ESV)
A worthless person, a wicked man, goes about with crooked speech, winks with his eyes, singals with his feet, points with his finger, with perverted heart devises evil, continually sowing discord;
therefore calamity will come upon him suddenly; in a moment he will e broken beyond healing.
There are six things that the Lord hates, seven that ar an abomination to him:
haughty eyes, a lying tongue, and hands that shed innocent blood,
a heart that devises wicked plans, feet that make haste to run to evil,
a false withness who breathes out lies, and one who sows discord among brothers.
- Proverbs 6:12-19
