He showed him the ‘reward of the bride’ (agra) de-khalah [Var. of the Shekhinah]. And She is the ‘heart of the fire’ between the thorns, who are the wicked, when they oppress the Shekhinah and Israel. Their reward is ‘ending’ (kalah). Shekhinah, the khalah (bride), exits from amongst them. And the ‘groom’ shall arrive for Her sake, and this is ‘the reward of the conference (kalah) is the crush’,liiiBT Berakhot 6b and He will redeem them from exile, because of Her.
And the oppression of Israel by the mixed multitude in exile, hastens the redemption for them, while their easing of exilic conditions delays the redemption for Israel.
