John Gill Commentary Jeremiah 20:5

"Moreover I will give all the riches of this city, and all the gains thereof, and all the precious things thereof, yea, all the treasures of the kings of Judah will I give into the hand of their enemies; and they shall make them a prey, and take them, and carry them to Babylon." — Jeremiah 20:5 (ASV)

Moreover, I will deliver all the strength of this city The fortifications of it; its towers, as the Syriac version; the riches of it, as the Targum; all its magazines and stores, in which its strength lay:

and all the labours thereof all the fruit of their labours; all their wealth and riches got by labour; all their goods in trade; all their manufactures and merchandise:

and all the precious things thereof all their plate and jewels, the rich furniture of their houses, and whatsoever was laid up in their treasures as rare and valuable:

and all the treasures of the kings of Judah will I give into the hand of their enemies which they in successive reigns had been laying up in store for years together; see (Isaiah 39:6) ; which shall spoil them, and take them, and carry them to Babylon ; make a prey of them, seize them as their property, and carry them away with them.
