Interpreters give different explanations of the beginning of this verse: some render it thus, "My eye comes down unto rivers of waters;" others, "My eye flows down unto rivers of waters," or, "rivers of waters flow down." But as I have explained elsewhere, the Prophet rather means, that his eye came down like rivers; and to come down, or to descend, is a metaphor for flowing down; for water, as it is well known, descends when it flows. And there is a change of number when he says, "My eye descends;" there is also raider-stood the particle of comparison, k, caph [1] The meaning is, that his eyes descended or flowed down as rivers. The last: word properly signifies divisions, but; he means that many streams flowed down, as though they were so many rivers. For the bruising, or the breach, of my people: the Prophet speaks here in his own person, though there is no doubt but that he exhorts all others to join him in his sorrow.

Mine eye runneth down - I weep incessantly.

Mine eye runneth down with rivers of waters,.... Denoting the greatness of his grief and trouble at the afflictions of his people, and the vast profusion of tears on that account. Here the prophet speaks in his own person, expressing the anguish of his soul he felt, and the floods of tears he shed:
for the destruction of the daughter of my people; for those that were slain of them, or carried captive; see Jeremiah 9:1. The Targum is,
"for the destruction of the congregation of my people.''

(Jeremiah 4:19).
