And I will rejoice in Jerusalem, and joy in my people: and the voice of weeping shall be no more heard in her, nor the voice of crying. The voice of weeping, etc. - "Because of untimely deaths shall no more be heard in thee; for natural death shall not happen till men be full of days; as it is written, Isaiah 65:20 : There shall be no more thence an infant of days, i.e., the people shall live to three or five hundred years of age, as in the days of the patriarchs; and if one die at one hundred years, it is because of his sin; and even at that age he shall be reputed an infant; and they shall say of him, An infant is dead. These things shall happen to Israel in the days of the Messiah." - Kimchi.
