But on that day I will give special treatment to the land of Goshen, where My people live; no swarms of flies will be found there. In this way you will know that I, the LORD, am in the land.
Jewish Publication Society of America Version (JPS1917) - Exodus 8:22 >(8-18) And I will set apart in that day the land of Goshen, in which My people dwell, that no swarms of flies shall be there; to the end that thou mayest know that I am the LORD in the midst of the earth.
