What is the significance of the Name Keil Shakai that the Pasuk uses here:
Rashi: It means 'the G-d who possesses all the means' - in this case to fulfill the blessing that He confers upon whoever He blesses. 1
This is the Name that Hashem used vis-a-vis the Avos, who did not live to see the fulfillment of those blessings (See Rashi at the beginning of Va'eira).
