He must have. The landowner or tenant isn't plowing at this point in the production cycle: all the human laborers and draft animals are involved in the harvest.
In traditional societies, gleaning was a right guaranteed to the poor. It was unlawful (or at least seriously inappropriate) for a farmer to send his own laborers to pick up the bits the main harvesting process missed. So the poor - usually widows or abandoned women - had to work, but they were guaranteed there would be something for them.
Except Boaz told his laborers to leave extra for Ruth on purpose.
Back in the days when I read National Geographic, I read an article that was about hunting dogs and the author referred to, “braying hounds”, not likely a typo as he did it several times in the article.
I am sure that you know better but for the unaware, donkeys bray, hounds bay.
Probable the author of this article may be a fine art critic but what he knows about farming would fit in a thimble.
