20 and Jehovah strengtheneth the heart of Pharaoh, and he hath not sent the sons of Israel away.
21 And Jehovah saith unto Moses, `Stretch out thy hand towards the heavens, and there is darkness over the land of Egypt, and the darkness is felt.'
22 And Moses stretcheth out his hand towards the heavens, and there is darkness--thick darkness in all the land of Egypt three days;
23 they have not seen one another, and none hath risen from his place three days; and to all the sons of Israel there hath been light in their dwellings.'
24 And Pharaoh calleth unto Moses and saith, `Go ye, serve Jehovah, only your flock and your herd are stayed, your infants also go with you;'
25 and Moses saith, `Thou also dost give in our hand sacrifices and burnt-offerings, and we have prepared for Jehovah our God;
26 and also our cattle doth go with us, there is not left a hoof, for from it we do take to serve Jehovah our God; and we--we know not how we do serve Jehovah till our going thither.'
