'Threatening' in the Bible

And in the morning, ‘It will be stormy today, for the sky is red and has a threatening look.’ You know how to interpret the appearance of the sky, but cannot interpret the signs of the times?

Now Saul, still breathing threats and murder against the disciples of the Lord [and relentless in his search for believers], went to the high priest,

For I am convinced [and continue to be convinced—beyond any doubt] that neither death, nor life, nor angels, nor principalities, nor things present and threatening, nor things to come, nor powers,

whether Paul or Apollos or Cephas (Peter) or the world or life or death or things present or things to come; all things are yours,

You masters, do the same [showing goodwill] toward them, and give up threatening and abusive words, knowing that [He who is] both their true Master and yours is in heaven, and that there is no partiality with Him [regardless of one’s earthly status].
