'Grain' in the Bible

Ruth the Moabitess said to Naomi, "Let me now go to the field, and glean among the ears of grain after him in whose sight I shall find favor." She said to her, "Go, my daughter."

At meal time Boaz said to her, "Come here, and eat of the bread, and dip your morsel in the vinegar." She sat beside the reapers, and they reached her parched grain, and she ate, and was satisfied, and left some of it.

When Boaz had eaten and drunk, and his heart was merry, he went to lie down at the end of the heap of grain. She came softly, uncovered his feet, and laid her down.
