'Instant' in the Bible

But the Kohathites shall not go in to see the holy things, even for an instant, or they will die.”

But the multitude of your enemies [that assault you] will become like fine dust,And the multitude of the tyrants like the chaff which blows away;And it will happen in an instant, suddenly [that your enemy is destroyed].

Therefore this wickedness [this sin, this injustice, this wrongdoing] will be to youLike a crack [in a wall] about to fall,A bulge in a high wall,Whose collapse comes suddenly in an instant,
