R. Chanina, the son of the brother of R. Yehoshua says: It is written (Devarim 32:3) "When I call upon the name of the L–rd" — the blesser; "give grandeur to our G–d" — the answerers. And what do they answer? "Blessed is the L–rd who is blessed forever." And when he mentions His name, they respond "Blessed is the name of the glory of His kingdom forever." And thus did David say (Psalms 34:4) "Exalt the L–rd with me, and let us extol His name forever."
