Isaiah 41:15
King James Version
Behold, I will make thee a new sharp threshing instrument having teeth: thou shalt thresh the mountains, and beat them small, and shalt make the hills as chaff.
Isaiah 41:15 in context
For I the LORD thy God will hold thy right hand, saying unto thee, Fear not; I will help thee.
Fear not, thou worm Jacob, and ye men of Israel; I will help thee, saith the LORD, and thy redeemer, the Holy One of Israel.
Behold, I will make thee a new sharp threshing instrument having teeth: thou shalt thresh the mountains, and beat them small, and shalt make the hills as chaff.
Thou shalt fan them, and the wind shall carry them away, and the whirlwind shall scatter them: and thou shalt rejoice in the LORD, and shalt glory in the Holy One of Israel.
When the poor and needy seek water, and there is none, and their tongue faileth for thirst, I the LORD will hear them, I the God of Israel will not forsake them.
