"Counting of the omer;" An omer is a biblical measurement of grain. The counting of the omer is 49-day period that begins on the second night of Passover during which each day is counted with a blessing. On the 50th day, the Festival of Shavuot is observed.
A celebration specific to the holiday of Shavuot, it includes a late-night – or even all-night – study of Torah and Jewish texts that commemorates receiving the Torah at Mount Sinai.
Literally, “the time of the giving of our Torah.” This refers to the holiday of Shavuot.
Literally, “head of the month.” Rosh Chodesh marks the beginning of each Hebrew month when there is a new moon (when there is no moon visible in the sky).
Literally, “four species.” The Torah specifies four species to bring together on Sukkot. The four species are: lulav (branches of palm trees), etrog (citron), hadasim (myrtle branches), and aravot (willows) (Leviticus 23:40).
