KJV: And they shall hearken to thy voice: and thou shalt come, thou and the elders of Israel, unto the king of Egypt, and ye shall say unto him, The LORD God of the Hebrews hath met with us: and now let us go, we beseech thee, three days' journey into the wilderness, that we may sacrifice to the LORD our God.
NASB: "They will pay heed to what you say; and you with the elders of Israel will come to the king of Egypt and you will say to him, 'The LORD, the God of the Hebrews, has met with us. So now, please, let us go a three days' journey into the wilderness, that we may sacrifice to the LORD our God.'
KJV: Then the LORD said unto Moses, Now shalt thou see what I will do to Pharaoh: for with a strong hand shall he let them go, and with a strong hand shall he drive them out of his land.
NASB: Then the LORD said to Moses, "Now you shall see what I will do to Pharaoh; for under compulsion he will let them go, and under compulsion he will drive them out of his land."
KJV: Behold, to morrow about this time I will cause it to rain a very grievous hail, such as hath not been in Egypt since the foundation thereof even until now.
NASB: "Behold, about this time tomorrow, I will send a very heavy hail, such as has not been seen in Egypt from the day it was founded until now.
KJV: Send therefore now, and gather thy cattle, and all that thou hast in the field; for upon every man and beast which shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die.
NASB: "Now therefore send, bring your livestock and whatever you have in the field to safety. Every man and beast that is found in the field and is not brought home, when the hail comes down on them, will die."'"
