Yea, I will give diligence that at every time ye may be able after my decease to call these things to remembrance.

And I will make every effort to ensure that after my departure, you will be able to recall these things at all times.

and I will be diligent that also at every time ye have, after my outgoing, power to make to yourselves the remembrance of these things.

but I will use diligence, that after my departure ye should have also, at any time, [in your power] to call to mind these things.
