시편 51:17 탈무드 참조: Jerusalem Talmud Berakhot & Berakhot

Rebbi Yose from Sidon¹⁸⁷A student of Rebbi Jeremiah, from the city of Sidon. The statements of R. Yoḥanan are in Babli 9b. There the requirement of recitation of these verses is noted as “institutions of the Rabbis”; the Babli would not tolerate the action of Rebbi Yudan. in the name of Rebbi Yoḥanan: Before one’s prayer one says (Ps. 51:17) “Master, open my lips that my mouth may proclaim Your praise.” After one’s prayer, one says (Ps. 19:15): “May the sayings of my mouth be agreeable and the thoughts of my heart, before You, my Rock and my Redeemer.” Rebbi Yudan used to say both of them before his prayer.

" They answer: Since the Rabbis instituted the prayer "Cause us, etc.," it is to be considered part of the Ge'ullah. If thou dost not admit this, how is it possible to affect the same union in the morning service ; for lo, R. Johanan has said : Before the Tefillah one says, "O Lord, open Thou my lips" (Ps. li. 17), and at its conclusion, "Let the words of my mouth... be acceptable" (ibid. xix. 15) !

How was he able to unite them? For lo, R, Johanan has said : At the commencement of the Tefillah one should say "O Lord, open Thou my lips" (Ps. li. 17) and at the conclusion "Let the words of my mouth etc." (ibid. xix. 15) !
