What do grandmother and mother disagree on over Benjamin?

The next day, Saul’s grandmother prepares Ben’s body for burial while the rest of the family mourns. She plans a traditional burial, where the body will be laid on the earth in a high place. His mother objects furiously, calling Naomi a heathen, and insists that Ben receive a Christian burial instead. Naomi tries to change her mind, and her husband’s, but they decide to take the body and leave to find a priest.
