Reply To: 2 Luchos on Shovuos?

Maybe you should ask, Why is the Kriyas HaTorah of Shavuos morning the Aseres HaDibros?
The Kabolas HaTorah, Ma’amad Har Sinai was 50 days after Yetzios Mitzrayim. There we all HEARD the ASERES HA’DIBROS from HASHEM. The luchos with the aseres hadibros were received 40 days later (17 Tammuz), and then again Yom Kippur (10 Tishrei).
