תניא אמר רב 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 יה"ר מלפניך שיכבשו רחמיך את כעסך ויגולו רחמיך על מדותיך ותתנהג עם בניך במדת הרחמים ותכנס להם לפנים משורת הדין ונענע לי בראשו

It was taught; Rabbi Yishmael the son of Elisha said: "I once entered into the inner most [part of the sanctuary], to offer incense, and I saw Akatrie-l K-ah (a name referring to the crown of God), the Lord of Hosts, seated upon a high and exalted throne, He said to me, 'Yishmael my son, bless Me!' I said, 'May it be Your will that that Your mercy suppresses Your anger, and that Your mercy prevail over Your other attributes, and that You deal with Your children with the attribute of mercy, and that You deal with them beyond the letter of the law.' And He nodded to me with His head.
