'Churns' in the Bible

For this reason my stomach churns; cramps overwhelm me like the contractions of a woman in labor. I am disturbed by what I hear, horrified by what I see.

I am the Lord your God, who churns up the sea so that its waves surge. The Lord who commands armies is his name!

Destruction, devastation, and desolation! Their hearts faint, their knees tremble, each stomach churns, each face turns pale!
