What does Exodus 9:19 mean?

Now therefore send, hasten in thy cattle and all that thou hast in the field; for every man and beast that shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die.

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.

Now therefore send, hasten in thy cattle and all that thou hast in the field; for every man and beast that shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die.

Then send quickly and get in your cattle and all you have from the fields; for if any man or beast in the field has not been put under cover, the ice-storm will come down on them with destruction.

`And, now, send, strengthen thy cattle and all that thou hast in the field; every man and beast which is found in the field, and is not gathered into the house--come down on them hath the hail, and they have died.'

Send therefore now presently, and gather together thy cattle, and all that thou hast in the field; for men and beasts, and all things that shall be found abroad, and not gathered together out of the fields which the hail shall fall upon, shall die.

And now send, [and] secure thy cattle, and all that thou hast in the field: all the men and the cattle that are found in the field, and are not brought home — on them the hail shall come down, and they shall die.
