'Cruel' in the Bible

Watch out! The Day of the LORD is coming cruel, with wrath and fierce anger to turn the entire inhabited earth into a desolation and to annihilate sinners from it.

At the time, when the LORD gives you rest from your suffering, turmoil, and the cruel bondage which they forced you to serve,

I will hand the Egyptians over to the power of a cruel master, and a fierce king will rule over them," declares the Lord GOD of the Heavenly Armies.
