The New John Gill Exposition of the Entire BibleExodus 1:13
And the Egyptians made the children of Israel to serve
Or with breach F3, with what might tend to break
their strength; they laid heavier burdens upon them, obliged them to
harder service, used them more cruelly and with greater fierceness,
adding to their hard service ill words, and perhaps blows.
F3 (Krpb) "in fractione", Cajetan. apud Rivet.
