'Bowels' in the Bible

I am poured out like water, and all my bones are out of joint: my heart is like wax; it is melted in the midst of my bowels.

By thee have I been holden up from the womb: thou art he that took me out of my mother's bowels: my praise shall be continually of thee.

As he clothed himself with cursing like as with his garment, so let it come into his bowels like water, and like oil into his bones.
