Matthew Henry on Ruth 3:6-13
Here is, I. Boaz's good management of his common affairs. It is probable, according to the common usage, 1. When his servants winnowed, he was with them, and had his eye upon them, to prevent, not their stealing any of his corn (he had no reason to fear that), but their waste of it through carelessness in the winnowing of it.

See on Rut 2:20 (note). Even to the present day, when a Jew marries a woman, he throws the skirt or end of his talith over her, to signify that he has taken her under his protection.
