Isaiah 41:14-15 ESV
Fear not, you worm Jacob,
you men of Israel!
I am the one who helps you, declares the LORD;
your Redeemer is the Holy One of Israel.
Behold, I make of you a threshing sledge,
new, sharp, and having teeth;
you shall thresh the mountains and crush them,
and you shall make the hills like chaff
