The part this in the midweek meeting had a LOT of questions about what a goad is. Probably 10 of 15 minutes spent on it. And they said it was a stick with a metal point, which I doubt what with metal being costly, and a sharpened stick would do as well.
Maybe next week we can learn about whips as in "we will keep whipping you until morale improves". Or how about the kindly yoke and light load. For advanced students there can be 6 and 8 letter words.
