The “Shtei HaLechem” are brought on Shavuos accompanied by 1 bull, 2 ram, 9 sheep and a goat.
In the davenningprayers for Shavuos (excluding piyyutim) the only mention of the “Shtei HaLechem”any of that is in the verse introducing the Musaf offering - וביום הבכורים בהקריבכם מנחה חדשה לה׳ בשבעתיכם מקרא קדש יהיה לכם כל מלאכת עבדה לא תעשו .
Why do the “Shtei HaLechem” not play a prominent part in the davenningprayers for Shavuos?
