Leviticus 15:25 Commentary - Ellicott's Commentary for English Readers (Old and New Testaments)

(25) Have an issue . . . many days.—The last case is that of a chronic issue, arising from a derangement in the constitution. This is the kind of complaint from which the woman suffered who came to Christ (Mat. 9:20; Luk. 8:44). As long as she suffered from it, which lasted sometimes for many years, she defiled and was defiling in the same way as in her menses.
