Exodus 9:1-3

Young's Literal Translation

9 And Jehovah saith unto Moses, `Go in unto Pharaoh, and thou hast spoken unto him, Thus said Jehovah, God of the Hebrews, Send My people away, and they serve me,

² for, if thou art refusing to send away, and art still keeping hold upon them,

³ lo, the hand of Jehovah is on thy cattle which [are] in the field, on horses, on asses, on camels, on herd, and on flock -- a pestilence very grievous.
