'Bitter' in the Bible

And the priest shall set the woman before Jehovah, and uncover the woman's head, and put the memorial oblation in her hands, which is the jealousy offering; and in the hand of the priest shall be the bitter water that bringeth the curse.

And the priest shall adjure her, and say unto the woman, If no man have lain with thee, and if thou hast not gone astray in uncleanness, in being with another instead of thy husband, be free from this bitter water that bringeth the curse.

And the priest shall write these curses in a book, and shall blot them out with the bitter water,

and he shall cause the woman to drink the bitter water that bringeth the curse, that the water that bringeth the curse may enter into her for bitterness.

In the second month, on the fourteenth day, between the two evenings, shall they hold it; with unleavened bread and bitter herbs shall they eat it.
