'Grain' in the Bible

And Ruth the Moabitess said to Naomi, “Please let me go to the field and glean among the ears of grain after one [of the reapers] in whose sight I may find favor.” Naomi said to her, “Go, my daughter.”

At mealtime Boaz said to her, “Come over here and eat some bread and dip your bread in the vinegar.” So she sat beside the reapers; and he served her roasted grain, and she ate until she was satisfied and she had some left [for Naomi].

When Boaz had eaten and drunk and his heart was happy, he went to lie down at the end of the stack of grain. Then Ruth came secretly, and uncovered his feet and lay down.
