אֲ֭דֹנָי שְׂפָתַ֣י תִּפְתָּ֑ח וּ֝פִ֗י יַגִּ֥יד תְּהִלָּתֶֽךָ׃
Panginoon, buksan mo ang aking mga labi, at ipahahayag ng aking bibig ang iyong papuri.

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.

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) !
