'Threatening' in the Bible

And He has carried out completely His [threatening] words which He had spoken against us and against our rulers [the kings, princes, and judges] who ruled us, to bring on us a great tragedy; for under the whole heaven there has not been done anything [so dreadful] like that which [He commanded and] was done to Jerusalem.

Then a mighty [warlike, threatening] king will arise who will rule with great authority and do as he pleases.
