Exodus 5:1-3

JPS_ASV_Byz(i) 1 And afterward Moses and Aaron came, and said unto Pharaoh: 'Thus saith the LORD, the God of Israel: Let My people go, that they may hold a feast unto Me in the wilderness.' 2 And Pharaoh said: 'Who is the LORD, that I should hearken unto His voice to let Israel go? I know not the LORD, and moreover I will not let Israel go.' 3 And they said: 'The God of the Hebrews hath met with us. Let us go, we pray thee, three days' journey into the wilderness, and sacrifice unto the LORD our God; lest He fall upon us with pestilence, or with the sword.'
