'Threatening' in the Bible

And in the morning, ‘Today will be stormy because the sky is red and threatening.’ You know how to read the appearance of the sky, but you can’t read the signs of the times.

So when he saw that he could gain nothing, but that on the contrary there was a riot threatening, he called for water and washed his hands in sight of them all, saying, "I am not responsible for this murder: you must answer for it."
