'Strengthened' in the Bible

Then the church throughout Judea, Galilee, and Samaria experienced peace and thus was strengthened. Living in the fear of the Lord and in the encouragement of the Holy Spirit, the church increased in numbers.

They strengthened the souls of the disciples and encouraged them to continue in the faith, saying, "We must enter the kingdom of God through many persecutions."

Both Judas and Silas, who were prophets themselves, encouraged and strengthened the brothers with a long speech.

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