Jeremiah 9:18

And let them make haste, and take up a wailing for us
Deliver out a mournful song, as the Arabic version; setting forth their miseries and distresses, and affecting their minds with them. The prophet puts himself among the people, as being a party concealed in their sufferings, and sympathizing with them, as well as to show the certainty of then and how soon they would be involved in them: that our eyes may run down with tears, and our eyelids gush out with
waters;
or balls of the eye, as the Targum and Kimchi; these hyperbolical expressions are used to express the greatness of the calamity, and that no mourning was equal to it; see ( Jeremiah 9:1 ) .
