And through it (Hod): (Gen. 7:19) And the waters greatly prevailed... When Israel does not observe the covenant of circumcision, the nations of the world prevail, [who are ‘the raging waters’ ], but when they observe it, it is stated of them: (Gen. 8:5)... and the waters were continually decreasing, until the tenth month... – this is the Yod of circumcision, which is Malkhut, tenth of the ten sephirot. [and this is: (Gen. 9:13) My bow I have placed in the cloud... which is ‘covenant’ (bryt) ]
And of Ya’AQoV (Jacob) – with that [Var. with this] thigh – it is stated of him: (Gen. 32:32)... and he was limping on his thigh. For the letter Yod י had flown away from him, and he remained’AQEV (heel). And the mystery of the matter: (Gen. 3:15)... he will bruise your head, and you will bruise his heel.
