Exodus 5:2-3

ECB(i) 2 And Paroh says, Who is Yah Veh, that I hear his voice to send Yisra El away? I neither know Yah Veh nor send I Yisra El away. 3 And they say, Elohim of the Hebrews met with us: let us go, we beseech you, a journey of three days into the wilderness and sacrifice to Yah Veh our Elohim; lest he encounter us with pestilence or with the sword.
