Exodus 3:18 YLT

[18] `And they have hearkened to thy voice, and thou hast entered, thou and the elders of Israel, unto the king of Egypt, and ye have said unto him, Jehovah, God of the Hebrews, hath met with us; and now, let us go, we pray thee, a journey of three days into the wilderness, and we sacrifice to Jehovah our God.
