Many siddurim capitalize the Yitzchak in Shochen Ad. Some draw attention to the Rivka. But why are either of them there? If you wanted to throw Yitzchak somewhere, why not minchah, which we midrashically derive from him.
bfi Ysharim titHalal
uvdivrei Tzadikim titBarach
uvilshon Chasidim titRomam
uv'kerev K'doshim titKadash
בְּפִי יְשָׁרִים תִּתְהַלָּל
וּבְדִבְרֵי צַדִּיקִים תִּתְבָּרַךְ
וּבִלְשׁוֹן חֲסִידִים תִּתְרוֹמָם
וּבְקֶרֶב קְדוֹשִׁים תִּתְקַדָּשׁ
PS. Sorry for the lack of Hebrew - I'm on my work computer and I could only find copyable chol davening. Feel free to edit / change to the Hebrew / add English.
