John Trapp on Jeremiah 49:23

Ver 23. Concerning Damaſcus] The chief City of Syria, ſo pleaſantly ſituate, ſo rich and luxurious, that one compareth it to Corinthus or Epheſus. Julian the Emperour in his Epiſtles, calleth it the City of Jupiter, and the Eye of the whole Eaſt. Tamerlan would not come into it, leſt he ſhould be detained there by the delights and delicacies of it. He deſtroyed it in a diſpleaſure, and built three Towers with the skuls of thoſe he had there ſlain (for a trophie) with ſingular skil. It was built again by the Seldan of Egypt, and is now poſſeſſed by the Turkes.

There is ſorrow on the ſea, it cannot be quiet] Or, There is ſorrow as upon the ſea which cannot reſt.
