'Bitter' in the Bible

And she cometh in unto the man of God, unto the hill, and layeth hold on his feet, and Gehazi cometh nigh to thrust her away, and the man of God saith, 'Let her alone, for her soul is bitter to her, and Jehovah hath hidden it from me, and hath not declared it to me.'

for Jehovah hath seen the affliction of Israel -- very bitter, and there is none restrained, and there is none left, and there is no helper to Israel;
