We must do our utmost to keep in our hearts the best we can remember the word of God:

“[BEHOLD, THE DAYS COME], saith the Lord GOD, [THAT I WILL SEND A FAMINE IN THE LAND, NOT A FAMINE OF BREAD, NOR A THIRST FOR WATER, BUT OF HEARING] the words of the LORD. And they shall wander from sea to sea, and from the north even to the east, they shall run to and fro to seek the word of the Lord, and shall not find it” (Amos 8:11-12).

“Thy word is a lamp unto my feet, and a light unto my path” (Psalm 119:105).

“Let not thine heart envy sinners: but be thou in the fear of the LORD all the day long” (Proverbs 23:17).

“When wisdom entereth into thine heart, and knowledge is pleasant unto thy soul” (Proverbs 2:10)

“For ever, O LORD, thy word is settled in heaven” (Psalm 119:89).

JESUS says: “It is written, that man shall not live by bread alone, but by every word of God” (Luke 4:4).
