'Lunch' in the Bible

Her mother-in-law noticed how much Ruth had gleaned and had brought back from what was left over from her lunch. So her mother-in-law quizzed her, "Where did you glean today? Where, precisely, did you work? May the one who took notice of you be blessed." So Ruth told her mother-in-law with whom she had worked. She said, "The man's name with whom I worked today is Boaz."
