1 Kings 17:14

For thus saith the Lord God of Israel
Whom the prophet perceived she had knowledge of, and faith in:

the barrel of meal shall not waste, neither shall the cruse of oil
fail;
that is, the meal in the barrel, and the oil in the cruse, by an hypallage, or change of words:

until the day that the Lord sendeth rain upon the earth;
which was assuring her the rain would be sent, and that the Lord, who had the sole command of it, would send it; and that, until that time it should be sent, she would have no lack of provisions, and therefore need not scruple dressing for the prophet first.
