חָשַׁשׁ

Therefore as the fire devoureth the stubble, and the flame consumeth the chaff, so their root shall be as rottenness, and their blossom shall go up as dust: because they have cast away the law of the LORD of hosts, and despised the word of the Holy One of Israel.

Ye shall conceive chaff, ye shall bring forth stubble: your breath, as fire, shall devour you.
