4:23 Keep thy heart with all diligence; for out of it are the issues of life.
4:27 Turn not to the right hand nor to the left: remove thy foot from evil.
14:22 Do they not err that devise evil? but mercy and truth shall be to them that devise good.
22:11 He that loveth pureness of heart, for the grace of his lips the king shall be his friend.
