John Trapp on Lamentations 2:18

Ver. 18. Their heard cryed unto the Lord] i. e. They cryed ſeriouſly at leaſt, if not ſincerely. Some think it was not a cry of the Spirit for grace; but only of the Fleſh, for eaſe and freedom from affliction: wherefore the Prophet in the next words turneth to the walls of Jeruſalem which were now broken down, bidding them weep, ſith the people would not. And ſurely the ſtony walls of mens houſes, ſtanding with bells of water on their faces before foul weather, ſhall witneſſe againſt ſuch hard hearts as relent not, and ſo prevent not the terrible tempeſt of Gods wrath for their iniquities. There are that render and ſenſe the text thus, Their heart cryeth againſt the Lord, i. e. the adverſaries ſet their whole power to deviſe blaſphemy againſt God: let the Church therefore pray in hope to be heard and to ſpeed the better for the others inſolencies. Theſe by wall underſtand the people within the wall; Others O Mure, qui nunc es merae ruinae, O poor ſhattered wall; or O City which art now nothing but bare walls, without houſing and inhabitants.
