'Joke' in the Bible

Then Lot went out and spoke to his sons-in-law [who were] taking his daughters and said, "Get up! Go out from this place, because Yahweh [is going] to destroy the city!" But {it seemed like a joke} in the eyes of his sons-in-law.

And they themselves scoff at kings and rulers [are] a joke to them. They laugh at every fortification, and they heap up earth and take it.
