'Fierce' in the Bible

before the decree bring forth, before the day pass away as chaff, before the fierce anger of Jehovah come upon you, before the day of Jehovah's anger come upon you.

Therefore wait ye for me, saith Jehovah, until the day that I rise up to the prey; for my determination is to assemble the nations, that I may gather the kingdoms together, to pour upon them mine indignation, all my fierce anger: for all the earth shall be devoured with the fire of my jealousy.
