'Joking' in the Bible

So Lot went out and spoke to his sons-in-law, who were [betrothed, and legally promised] to marry his daughters, and said, “Get up, get out of this place, for the Lord is about to destroy this city!” But to his sons-in-law he appeared to be joking.

So is the man who deceives his neighbor (acquaintance, friend)And then says, “Was I not joking?”
