'Seriously' in the Bible

And Lot went out and said to his sons-in-law, who were married to his daughters, Come, let us go out of this place, for the Lord is about to send destruction on the town. But his sons-in-law did not take him seriously.

And some of the rulers of Asia, being his friends, sent to him, requesting him seriously not to put himself in danger by going into the theatre.

Seriously requesting us that they might have a part in this grace of being servants to the needs of the saints:

Have no feeling of hate for him, but take him in hand seriously as a brother.
