We ask Hashem to set our lot with the righteous “forever”, that we should forever be in their company, and that we should forever be aiding them and emulating their ways, without any weakness or turning away from them forever. But moreover, in the merit of having associated with the Torah-scholars and having followed them all our lives, we also pray that the reward and blessing that accrues to them should also be “our lot”, both in this life and in the Afterlife – לעולם, forever.
