Jeremiah 46:25 - Matthew Poole's English Annotations on the Holy Bible

The Lord of hosts, the God of Israel, saith: these names are often in conjunction given unto God, the first signifying his power or ability to do what he either promiseth or threateneth, the other speaking his kindness and near relation to the Jews. Behold, I will punish the multitude of No: there are great critical disputes about this phrase, whether the word translated multitude signifies so, (as it doth Jeremiah 52:15) and if so, whether it should not be multitude from No; or whether it signifies the nourisher, (as some would have it,) because No (which some think is the same city with that at this time called Alexandria, being a great place of merchandise) nourished all the adjacent parts; but it is no easy thing to resolve the question, nor is the resolution of it of much moment to us. By those that trusted in Pharaoh the Jews are most probably meant, who all along in their prosperity put too much confidence in Egypt, and after that Jerusalem was taken some of them (as we before heard) fled into Egypt for sanctuary.
