My son, let not them depart from thine eyes: keep sound wisdom and discretion:
Let not wisdom, discretion and understanding depart from your eyes means that they are things you primarily learn, acquire and retain from reading. And of all the books that exist and will ever be in the world, the bible, the word of GOD, is the most powerful book, a must read and a must believe, a companion for life and living, a compendium of the divine life.
Read it from cover to cover and read it again and again from cover to cover. Do this all your life and verse 22-24 will be your testimony.
 So shall they be life unto thy soul, and grace to thy neck.
 Then shalt thou walk in thy way safely, and thy foot shall not stumble.
 When thou liest down, thou shalt not be afraid: yea, thou shalt lie down, and thy sleep shall be sweet.
NLT for they will refresh your soul. They are like jewels on a necklace. They keep you safe on your way, and your feet will not stumble. You can go to bed without fear; you will lie down and sleep soundly.
When you travel through with the word of GOD as your guide, the error margin of your life will begin to reduce. You will find yourself making less mistakes, and taking more precise and accurate steps.
MSG They’ll keep your soul alive and well, they’ll keep you fit and attractive. You’ll travel safely, you’ll neither tire nor trip. You’ll take afternoon naps without a worry, you’ll enjoy a good night’s sleep.
And if you struggle with insomnia or worries and anxieties at night that hinders you from getting good rest, reading and meditating on scriptures before you sleep is always a saver.
The word of GOD is that precious!!!
Keep it before your eyes.
And let it be guide.
