'Strongly' in the Bible

And for this purpose I am working, using all my strength by the help of his power which is working in me strongly.

I make this request more strongly, in the hope of coming back to you more quickly.

My loved ones, while my thoughts were full of a letter which I was going to send you about our common salvation, it was necessary for me to send you one requesting you with all my heart to go on fighting strongly for the faith which has been given to the saints once and for ever.
