John Gill Commentary 2 Kings 7:16

"And the people went out, and plundered the camp of the Syrians. So a measure of fine flour was [sold] for a shekel, and two measures of barley for a shekel, according to the word of Jehovah." — 2 Kings 7:16 (ASV)

And the people went out and spoiled the tents of the Syrians, &c.] Of their riches, and of their provisions; of which there was such a plenty, not only for present use, but for sale,

so that a measure of fine flour was sold for a shekel

according to the word of the Lord; by Elisha, (2 Kings 7:1).
