'Bitterness' in the Bible

So the Spirit lifted me up, and took me away; and I went in bitterness, in the heat of my spirit; and the hand of Jehovah was strong upon me.

Sigh therefore, thou son of man; with the breaking of thy loins and with bitterness shalt thou sigh before their eyes.

and they shall make themselves bald for thee, and gird them with sackcloth, and they shall weep for thee in bitterness of soul with bitter mourning.
