Kabbalah zu Jirmejahu 2:34

About this sin it says, “Also your clothing is stained with the blood of the innocent and the poor” (Jeremiah 2:34), and also as we said above “slaughterers of children” (Isaiah 57:5) that he literally slaughters his children, and as Rabbi Shimon Bar Yochai says in Vayechi, which we quoted above. Therefore, he does not see the face of the Shechinah, since the Shechinah does not reveal Herself to him as She does to the rest of the Tzadikim, unless he does proper Teshuva, as we will explain later on. Until here is the summary of his words.
