ייִדישער מחשבֿה אויף עזרא 10:19

(5) When the humble man rebukes himself, exacts the Creator's justice upon himself of his own initiative, and voluntarily submits to it, even though no human authority has the power to enforce it - this points to his true humility before G-d as well as his lowliness and submission to Him, as written: "We have trespassed against our G-d, and have taken strange wives of the people of the land" (Ezra 10:2), and "they gave their hand to send away their wives" (Ezra 10:19).
