Musar sobre Génesis 22:16

We also find that the preamble of קריאה was used prior to the actual message in the case of the angel speaking to Abraham. What special proof of fondness does this expression indicate here in Leviticus where the Torah does not even link this form of address to some form of express compliment to Moses in contradistinction to the compliment paid to Abraham in Genesis 22,15 where the use of the word ויקרא is followed by an acknowledgment of why Abraham qualified for this special fondness G–d displayed for him? In that instance G–d explains that He swore an oath acknowledging Abraham's outstanding act of obedience.

אבל אנחנו עמך – It is a fact that the merit of our patriarchs will assist us, provided we conduct ourselves as their true descendants and follow in their footsteps. We are urged to do so in Songs of Songs 1,8: צאי לך בעקבי הצאן, "Contemplate the actions of your ancestors" (cf. Rashi). When we do this their merits will be merged with all those described by the author of our prayers as בני בריתך, because we are בני אברהם אהבך. The prayer continues to cite the promises G–d made to Abraham in return for his offering Isaac on the altar. The mystical dimension of humility is deeply intertwined with the mystical dimension of love. The three patriarchs symbolize the three kinds of perfection we have discussed, that of the soul, that of the body and that of the way we handle money. Abraham demonstrated the perfection of the soul when he offered Isaac, his only beloved son, as a total offering, something which entailed a total abrogation of self.
