זוהר בראשית — דף קנא ע”א

Rabbi Ḥiya explains that David asked forgiveness first for himself and then for all: when the wicked are many, the books of judgment are opened, hence “our transgressions, You will atone for them.” Jacob did not doubt the Holy One, blessed be He, but himself, fearing that a sin might prevent him from returning in peace. Rabbi Aha, Rabbi Yose, Rabbi Abba and Rabbi Elazar comment: Judgment will guard him until his return, and then he will include mercy within judgment; “this stone… shall be a pillar” and “house of God” designate the place of judgment, and the text also speaks of “the city of the great King.” Then Rabbi Ḥiya and Rabbi Ḥizkiya sit in the field of Ono; Rabbi Ḥiya, asleep, sees Elijah, who announces that Jerusalem is near destruction, and that the Torah, the tree of life, protects it as long as it is awakened below.
