Then the LORD said to Moshe, "Go in to Par`oh, and tell him, 'This is what the LORD, the God of the Hebrews, says: "Let my people go, that they may serve me.
For if you refuse to let them go, and hold them still,
behold, the hand of the LORD is on your cattle which are in the field, on the horses, on the donkeys, on the camels, on the herds, and on the flocks with a very grievous pestilence.
The LORD will make a distinction between the cattle of Yisra'el and the cattle of Mitzrayim; and there shall nothing die of all that belongs to the children of Yisra'el."'"
The LORD appointed a set time, saying, "Tomorrow the LORD shall do this thing in the land."
The LORD did that thing on the next day; and all the cattle of Mitzrayim died, but of the cattle of the children of Yisra'el, not one died.
Par`oh sent, and, behold, there was not so much as one of the cattle of the Yisra'elites dead. But the heart of Par`oh was stubborn, and he didn't let the people go.
