תניא אמר רבי ישמעאל בן אלישע פעם אחת נכנסתי להקטיר קטורת לפני ולפנים וראיתי אכתריאל יה ה׳ צבאות שהוא יושב על כסא רם ונשא ואמר לי ישמעאל בני ברכני אמרתי לו יהי רצון מלפניך שיכבשו רחמיך את כעסך ויגולו רחמיך על מדותיך ותתנהג עם בניך במדת הרחמים ותכנס להם לפנים משורת הדין ונענע לי בראשו וקמשמע לן שלא תהא ברכת הדיוט קלה בעיניך
Similarly, it was taught in a baraita that Rabbi Yishmael ben Elisha, the High Priest, said: Once, on Yom Kippur, I entered the innermost sanctum, the Holy of Holies, to offer incense, and in a vision I saw Akatriel Ya, the Lord of Hosts, one of the names of God expressing His ultimate authority, seated upon a high and exalted throne (see Isaiah 6).
And He said to me: Yishmael, My son, bless Me.
I said to Him the prayer that God prays: “May it be Your will that Your mercy overcome Your anger,
and may Your mercy prevail over Your other attributes,
and may You act toward Your children with the attribute of mercy,
and may You enter before them beyond the letter of the law.”
The Holy One, Blessed be He, nodded His head and accepted the blessing. This event teaches us that you should not take the blessing of an ordinary person lightly. If God asked for and accepted a man’s blessing, all the more so that a man must value the blessing of another man.
