Kenneth Copeland — Life And Prosperity Through Your Words

Joshua 1:8
KJV—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.
Moffatt—This lawbook you shall never cease to have on your lips; you must pore over it day and night, that you may be mindful to carry out all that is written in it, for so shall you make your way prosperous, so shall you succeed.
NIV—Do not let this Book of the Law depart from your mouth; meditate on it day and night, so that you may be careful to do everything written in it. Then you will be prosperous and successful.
Matthew 12:34-37
KJV—Out of the abundance of the heart the mouth speaketh. A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things. But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
Amp—Out of the fullness—the overflow, the superabundance—of the heart the mouth speaks. The good man from his inner good treasure flings forth good things, and the evil man out of his inner evil storehouse flings forth evil things. But I tell you, on the day of judgment men will have to give account for every idle (inoperative, non-working) word they speak. For by your words you will be justified and acquitted, and by your words you will be condemned and sentenced.
Moffatt—The mouth utters what the heart is full of. The good man brings good out of his good store, and the evil man brings evil out of his store of evil. I tell you, on the day of judgment men will have to account for every careless word they utter; for by your words you will be acquitted, and by your words you will be condemned.
