'Strong' in the Bible

In the measure of my strong hope and belief that in nothing will I be put to shame, but that without fear, as at all times, so now will Christ have glory in my body, by life or by death.

Only let your behaviour do credit to the good news of Christ, so that if I come and see you or if I am away from you, I may have news of you that you are strong in one spirit, working together with one soul for the faith of the good news;

So my brothers, well loved and very dear to me, my joy and crown, be strong in the Lord, my loved ones.
