The isha (woman) when she gives birth, has agmat nefesh (grief), [YESHAYAH 13:8; 21:3; 26:17; MICHOH 4:9; HOSHEA 13:13] because the sha'ah (hour, time) of her has come. But when she gives birth to the yeled, she no longer has zikaron of the Tribulation because of the naches that an ish was born into the Olam Hazeh.
