'Misfortune' in the Bible

Why should the Egyptians speak, and say, For misfortune he has brought them out, to slay them on the mountains, and to annihilate them from the face of the earth? Turn from the heat of thine anger, and repent of this evil against thy people!

Thou hast indeed smitten Edom, and thy heart has lifted thee up: boast thyself, and abide at home; for why shouldest thou contend with misfortune, that thou shouldest fall, thou, and Judah with thee?

Thou thinkest, Lo, thou hast smitten Edom; and thy heart has lifted thee up to boast: abide now at home; why shouldest thou contend with misfortune, that thou shouldest fall, thou and Judah with thee?

Is not calamity for the unrighteous? and misfortune for the workers of iniquity?
