“Else, if thou wilt not let my people{H5971} go,{H7971} behold, I will send{H7971} swarms{H6157} of flies upon thee, and upon they servants,{H5650} and upon thy people,{H5971} and into thy houses:{H1004} and the houses{H1004} of the Egyptians{H4714} shall be full{H4390} of swarms{H6157} of flies, and also the ground{H127} whereon they are.”
