Moshe stretched forth his rod over the land of Egypt, and the LORD brought an east wind on the land all that day, and all the night; and when it was morning, the east wind brought the locusts.
The LORD turned an exceeding strong west wind, which took up the locusts, and drove them into the Sea of Suf. There remained not one arbeh in all the borders of Egypt.
For who knows what is good for man in life, all the days of his vain life which he spends like a shadow? For who can tell a man what will be after him under the sun?
Whereas you don't know what your life will be like tomorrow. For what is your life? For you are a vapor, that appears for a little time, and then vanishes away.
