Ruth 1:20-21

20She said to them, “Do not call me Naomi;
 Naomi means pleasant
call me bMara,
 Mara means bitter
for the Almighty has dealt very bitterly with me.
21 dI went away full, and the Lord has brought me back empty. Why call me Naomi, when the Lord has testified against me and the Almighty has brought calamity upon me?”

2 Kings 4:27

27And when she came eto the mountain to the man of God, she caught hold of his feet. And Gehazi came to push her away. But the man of God said, “Leave her alone, for she is in bitter distress, and the Lord has hidden it from me and has not told me.”
