Tremble, and do not sin; Meditate in your heart upon your bed, and be still. Selah.
"This book of the law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it; for then you will make your way prosperous, and then you will have success.
Take pains with these things; be absorbed in them, so that your progress will be evident to all.
Let the words of my mouth and the meditation of my heart Be acceptable in Your sight, O LORD, my rock and my Redeemer.
