'Learned' in the Bible

Now after an interval of about three hours his wife came in, not knowing what had happened.

And the hand (the power and presence) of the Lord was with them, and a great number who believed turned to the Lord [for salvation, accepting and drawing near to Jesus as Messiah and Savior].

But when the Jews of Thessalonica learned that the word of God [concerning eternal salvation through faith in Christ] had also been preached by Paul at Berea, they came there too, agitating and disturbing the crowds.

This man was seized [as a prisoner] by the Jews and was about to be killed by them, when I came upon him with the troops and rescued him, having learned that he was a Roman citizen.
