Q. In Shemone Esre we say Ata Chonen Chochma Bina Veda’at, but at the end we only say only Chonen Hada’at. Why do we omit Chochma and Bina.
Thanks.

A. A general rule in the brochos of the Amida (and others) is that the brochos end using the same or similar words as they begin. (see Tosafos Brochos 10a, peirush Eshel Avrohom ad. loc.) Just as the earlier brocho, of Ata Kadosh finishes with the word Hakadosh and the one after, Hashivenu ends with Teshuva, so Ata Chonen begins with Daas and finishes likewise.
