ציטירנדיקער פּירוש אויף בראשית 27:28

It is also explained by way of that which the verse states (I Kings 18:39), "The Lord is God;" and the intention [of this] is that even if the name Elohim relates to [strict] justice, nonetheless it is [indicative of] mercy. And all of the names of the Holy One, blessed be He, intend, for the good, together to do good and to do kindness; but from the angle of the acts of the backward ones, judgment came out to chastise whoever is fitting to be chastised. And besides this, the attribute of the name, Elohim, is also to do good. And this is what it is saying, "In the beginning, created Elohim," since the name Elohim, did good and created the world to have grace and mercy and to do good to those that dwell in the heavens and the earth and there is no greater mercy than this. And this is what the verse states (Genesis 27:28), "And Elohim will give to you;" behold, that also the name Elohim does good to the good by way of a free gift; but evildoers cause Elohim to give them chastisement. And in the anticipated future, so will it be, [that] the Lord (the name associated with mercy) shall be one and His name shall be one.

“Of the dew of heaven and the fat of the earth” [Genesis 27:28]. Amalek was descended from Esau, who wanted to take revenge on Jacob, who had taken away the blessings. Therefore, we praise God with the first fruits and say that the first fruits are called “the first fruits of the soil” [26:10]. Amalek was called “a leading nation is Amalek” [Numbers, 24:20]. His [Balaam’s] advice did not succeed and Israel conquered the land. “The fat of the earth” [Genesis, 27:28]. We have the good fruits from God who is called First, the first, before the first ones. They praised God for the lovingkindness that the Holy One helped us escape from Amalek and in addition we mentioned the other good things that God has helped us.⁶Zeror ha-Mor, Deuteronomy, 26:2.

אחי יהי לך אשר לך , “keep what is yours my brother.” Bereshit Rabbah 78,11 comments on these words of Esau that up until that moment Yaakov still entertained doubts whether the blessings were securely his. Now that he heard Esau acknowledge “keep what is yours,” he was visibly relieved concerning the validity of these blessings. He based this on the precise wording of Esau’s comment which contained ten letters. These ten words corresponded to the ten blessings which formed the blessing commencing with the words ויתן לך (Genesis 27,28-29).

אף שמיו יערפו טל ALSO HIS HEAVENS SHALL DRIP DEW — Also Isaac’s blessing will be added to Jacob’s blessing: “And God shall give thee of the dew of heaven, etc.” (Genesis 27:28) (cf. Sifrei Devarim 356:7).
