John Trapp on Lamentations 5:19

Ver. 19. Thou O Lord remaineſt for ever] Alioqui totus totus deſperaſſem, as that good man ſaid once in like caſe: Otherwiſe I ſhould have but ſmall joy of my life. But thou art everlaſting and invariable in eſſence, truth, will and promiſes: This is mine Anchor-hold.

Thy throne from generation to generation] i. e. Thy moſt equal and righteous ordering of all things, utut nobis quaedam confuſiuſculè currere videantur, though ſome things may ſeem to us to be ſomewhat confuſedly carried, and even to run on wheels, yet it ſhall one day appear that there was a wheel within a wheel, Ezek. 1. that is, an over ruling and all-diſpoſing Providence.
