'Bowels' in the Bible

My bowels, my bowels! I am pained at the walls of my heart, Make a noise for me doth My heart, I am not silent, For the voice of a trumpet I have heard, O my soul -- a shout of battle!

A precious son is Ephraim to Me? A child of delights? For since My speaking against him, I do thoroughly remember him still, Therefore have My bowels been moved for him, I do greatly love him, An affirmation of Jehovah.
