Israel Sabba Tevuna

SABBA, grandfather, relates to white and wisdom which is CHOCHMA. It therefore relates to a vessel of reception.

But BINAH is defining herself in the nature of bestowal. In order to actualize bestowal she needs to give birth to a body, ZEER ANPIN and MALCHUT that will be able to receive life, CHOCHMA, without changing her nature.

This is how it's dividing itself. ABBA and IMMA are the nature of BINAH itself and the action of bestowing life, wisdom, to the 'createes', is an action of actualizing the will of the Creator.

Wishing to be like the Creator is CHESED, the actual nature of BINAH, but wishing to bestow, is the opposite of her nature, it's not coming closer to the Creator but getting away, extending. That is ISRAEL SABBA TEVUNA.

The two natures that will allow BINAH to teach, and allow the 'createe' to receive and be part of the will of the Creator, which is to bestow goodness to the 'createes'.
