Zohar
And regarding this [it is written]: "And I will do due to My name" (Ezekiel 20:14) and also "Because of Me, because of Me I will do" (Isaiah 48:11). And if they do not return I will set on them a king whose decrees will be harsher than Pharaoh's, and they will return against their will. And this is what is written "return to Ad-nai your God" - truly up to YHV"H.
