Exodus 3:18-20

Young's Literal Translation

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.

¹⁹ `And I -- I have known that the king of Egypt doth not permit you to go, unless by a strong hand,

²⁰ and I have put forth My hand, and have smitten Egypt with all My wonders, which I do in its midst -- and afterwards he doth send you away.
