'Within' in the Bible

My child, if you receive my words, and store up my commands within you,

Do not let them depart from your sight, guard them within your heart;

For it is pleasing if you keep these sayings within you, and they are ready on your lips.

The one who hates others disguises it with his lips, but he stores up deceit within him.

When he speaks graciously, do not believe him, for there are seven abominations within him.
