כִּ֤י ׀ לֹא־תַחְפֹּ֣ץ זֶ֣בַח וְאֶתֵּ֑נָה ע֝וֹלָ֗ה לֹ֣א תִרְצֶֽה׃
주는 제사를 즐겨 아니하시나니 그렇지 않으면 내가 드렸을 것이라 주는 번제를 기뻐 아니하시나이다
Mishneh Torah, Prayer and the Priestly Blessing
Before reciting the first blessing in each of the services, one begins, "O Lord, open Thou my lips, and my mouth shall declare Thy praise," (Psalms 51:17) and after concluding the service, one adds, "Let the words of my mouth and the meditation of my heart be acceptable before Thee, O Lord, my Rock and my Redeemer," (Psalms 19:15), after which the worshipper steps backward.
