'Food' in the Bible

Then she set out with her daughters-in-law to return from the country of Moab, for she had heard in Moab how the Lord had taken care of His people [of Judah] in giving them food.

She picked it up and went into the city, and her mother-in-law saw what she had gleaned. Ruth also took out and gave to Naomi what she had saved after she [had eaten and] was satisfied.
