'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 Yahweh was strong on me.

Sigh therefore, you son of man; with the breaking of your thighs and with bitterness you will sigh before their eyes.

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