Kabbalah sa Jeremias 2:21: Zohar & Sha'arei Orah

What then do her mighty warriors do? They roar like lions, until their voice is heard by the Beloved above, and He knows that his Beloved is lovesick like himself, so that none of her beauty can be seen,

Now, because Yaakov merited that the Name HaShem-יהו״ה is called upon him, he therefore merited to give birth to twelve righteous tribes, corresponding to the twelve permutations of the Name HaShem-יהו״ה, blessed is He. Moreover, just as HaShem-יהו״ה is called “Truth-Emet-אמת,” so are the children of Yaakov called, “the seed of Truth-Zera Emet-זרע אמת,” meaning, the seed-Zera-זרע from which Truth-Emet-אמת comes forth from the source that they were hewn from, this being our forefather Yaakov, peace be upon him. About this the verse states,⁵⁴Jeremiah 2:21 “I planted you from a choice vine, entirely the seed of Truth-Zera Emet-זרע אמת.”
