Acts 14:3

Long time therefore abode they speaking boldly in the Lord, which gave testimony unto the word of his grace, and granted signs and wonders to be done by their hands.

Therefore they stayed there a long time, speaking boldly in the Lord, who testified to the word of his grace, granting signs and wonders to be done by their hands.

Long time therefore they tarried `there' speaking boldly in the Lord, who bare witness unto the word of his grace, granting signs and wonders to be done by their hands.

long time, indeed, therefore, did they abide speaking boldly in the Lord, who is testifying to the word of His grace, and granting signs and wonders to come to pass through their hands.

So Paul and Barnabas spent considerable time there, speaking boldly for the Lord, who affirmed the message of His grace by enabling them to perform signs and wonders.
