What did Boaz pour into Ruth's shawl before she left the threshing floor?

Answer: Six measures of barley

He gave her six measures of barley, saying, "Do not go back to your mother-in-law empty-handed."

“And he told her, “Bring the shawl you are wearing and hold it out.” When she did so, he poured in six measures of barley and placed it on her. Then he went into the city.”— Ruth 3:15 (BSB)
