Proverbs 3:21

This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.

Let them not depart from thine eyes; keep them in the midst of thine heart.

Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons’ sons;

Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed;

He layeth up sound wisdom for the righteous: he is a buckler to them that walk uprightly.
