Ruth 2:17

‘ So she gleaned in the field until evening, and she beat out what she had gleaned, and it was about an ephah of barley.’

So Ruth continued to glean diligently until nightfall, after which she beat out what she had gleaned, and it came to about an ephah of barley. Due to the generosity and kindness of Boaz it was far more than she could have expected as a gleaner. An ephah was a vessel large enough to hold a small woman (Zechariah 5:6-10).
