Matthew Poole and continuators on Jeremiah 49:4

4 Wherefore gloriest thou in the vallies, thy flowing valley , O backsliding daughter ? that trusted in her treasures, saying, Who shall come unto me u?

It should seem that this Countrey was full of very fruitful vallyes, which we know are alwayes the most fertile places, lying lower and at greater distance from the Sun then Mountains, and also receiving at second hand the moisture that falls upon the Hills, and being usually watered with Rivers, from whence they may be called flowing Vallies either as flowing with receptacles of Water, or plenty of Corn, and Grass, though some read it (and it seems rather more agreeable to the Hebrew) thy Valley floweth, either with the blood of men slain, or floweth away, the fertility of it ceaseth or decayeth. Or, Floods of waters shall destroy the fruit of thy rich Vallies, &c.

Ammon having never been in Covenant with God, the word in the Heb. (though it comes from [non-Latin text not transcribed] which signifies to return) seemeth ill translated back sliding thou that hast turned thy self away from God. Thou that trustedst in thy riches, or in thy Vallies full of riches, and promisedst thy self security from the scituation of thy rich Countrey thinking none could come at thee.
