하박국 3:1 탈무드 참조: Megillah

On Shavuot, we read “Seven weeks”, and for haftarah from Habakuk (3:1-19). According to others, we read “In the third month” (Exodus 19:1-20:23), and for haftarah the account of the Divine Chariot (Ezekiel 1:1-28, 3:1-12). Nowadays that we keep two days, we act in accordance with both, but in the reverse order.
