Deuteronomy

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.

O how love I thy law! it is my meditation all the day.

I understand more than the ancients, because I keep thy precepts.

But his delight is in the law of the Lord; and in his law doth he meditate day and night.

Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
