Quotation for Psalms 148:7

What praise did they say? "Praise Hashem from the land, sea monsters and all depths... fruit trees and all cedars... Praise Hashem (Psalms 148:7-14)." One angel spoke up from the fire and said, "This (what they were learning) is the deed of the chariot." Rabban Yochanan the son of Zakkai stood and kissed him on the head, and said, "Blessed is Hashem, the G-d of Israel, who gave a son to Abraham our father who knows how to understand, to investigate, and to expound the deed of the chariot. There is one who expounds well but does not uphold well [and there is one who] upholds well but does not expound well. You expound well and uphold well. Praiseworthy are you, Abraham our forefather, for Elazar the son of Arakh has exited from your loins."
