Settle it therefore in your hearts, not to meditate beforehand how to answer:
Settle it therefore in your hearts, not to meditate before what ye shall answer:
Resolve and settle it in your minds not to meditate and prepare beforehand how you are to make your defense and how you will answer.
Make up your minds not to prepare your defense in advance.
Therefore, set this in your hearts: that you should not consider in advance how you might respond.
