In Nusach Ashkenaz we say at the end of each Amidah, a three phrase Yehi Ratzon for the rebuilding of the Bet HaMikdash (Temple).
Can anyone shed light on the authorship or derivation of this Yehi Ratzon?
The text is:[1]יְהִירָצוֹןמִלְּ֒פָנֶֽיךָיְהֹוָהאֱלֹהֵֽינוּוֵאלֹהֵיאֲבוֹתֵֽינוּשֶׁיִּבָּנֶהבֵּיתהַמִּקְדָּשׁבִּמְהֵרָהבְיָמֵֽינוּוְתֵןחֶלְקֵֽנוּבְּתוֹרָתֶֽךָ:
וְשָׁםנַעֲבָדְךָבְּיִרְאָהכִּימֵיעוֹלָםוּכְשָׁנִיםקַדְמוֹנִיּוֹת: [2]
וְעָרְ֒בָהלַיהוָֹהמִנְחַתיְהוּדָהוִירוּשָׁלָֽםִכִּימֵיעוֹלָםוּכְשָׁנִיםקַדְמוֹנִיּוֹת: [3]
[1] May it be thy will, O Lord our God, and God of our fathers that the temple be speedily rebuilt in our days, and grant us our portion in thy Law.
[2] And there we will serve you with awe, as in the days of old, and as in ancient years.
[3] Then shall the offering of Judah and Jerusalem be pleasant unto the Lord, as in the days of old, and as in ancient years.
[Translation from (UK) Authorised Daily Prayer Book, Second Edition, 1962].
[3] comes verbatim from Malachi 3:4.
[1] is similar to (but not identical with) this phrase from Pirkei Avot 5:20:יְהִירָצוֹןמִלְּפָנֶיךָיְיָאֱלֹהֵינוּשֶׁתִּבְנֶהעִירְךָבִּמְהֵרָהבְיָמֵינוּוְתֵןחֶלְקֵנוּבְתוֹרָתֶךָ:
[2] I have not yet found a source for [2].
And in any event what is the source for joining together these phrases and placing this Yehi Ratzon at the end of each Amidah.
I am aware of this post Yehi ratzon for the rebuilding of the Temple. I do not think mine is a duplicate of the earlier post
