After his prayer, Rav said the following:
May it be Your will, Lord our God,
that You grant us long life, a life of peace,
a life of goodness, a life of blessing,
a life of sustenance, a life of freedom of movement from place to place, where we are not tied to one place,
a life of dread of sin, a life without shame and disgrace,
a life of wealth and honor,
a life in which we have love of Torah and reverence for Heaven,
a life in which You fulfill all the desires of our heart for good.
And why did they see fit to institute that one says the blessing beginning with the words: Grant peace, after the Priestly Benediction? As it is written immediately following the Priestly Benediction: “And they shall put My name upon the children of Israel, and I will bless them” (Numbers 6:27). The Priestly Benediction is followed by God’s blessing, and the blessing of the Holy One, Blessed be He, is peace, as it is stated: “The Lord blesses His people with peace” (Psalms 29:11).
