Shemot 5:3-5 Orthodox Jewish Bible (OJB)
3 And they said, Elohei HaIvrim hath met with us; let us go, now, derech shloshet yamim into the midbar, and sacrifice unto Hashem Eloheinu; lest He fall upon us with dever (cattle disease), or with the cherev.
4 And Melech Mitzrayim said unto them, Why do ye, Moshe and Aharon, disturb the people from their works? Get you back unto your own sivlot (burdens).
5 And Pharaoh said, Hinei, the Am HaAretz now are many, and ye make them rest from their sivlot.
