Mara

In verses 6-22, we see Naomi leave Moab and return to her hometown, Bethlehem.

Orpah honors Naomi's guidance and returns to her family, but Ruth shares one of the classic statements of faith in verse 16:

Don't urge me to leave you or to turn back from you. Where you go I will go, and where you stay I will stay. Your people will be my people and your God my God.

Despite Ruth's loyalty, Naomi changes her name to Mara (lit. "bitter").
