'Strengthened' in the Bible

Then the church throughout all of Judea and Galilee and Samaria had peace, being strengthened. And living in the fear of the Lord and the encouragement of the Holy Spirit, it was increasing [in numbers].

Both Judas and Silas, who were also prophets themselves, encouraged and strengthened the brothers by a long message.

So the churches were being strengthened in the faith and were growing in number every day.
