Aseret ha-Devarim mobile for Shavuot

In the Torah, the so known as the Ten Commandements they are called Aseret ha-Devarim.  In rabbinical texts, they are referred to as Aseret ha-Dibrot. The words d'varim and dibrot come from the Hebrew root Dalet-Beit-Reish, meaning word, speak or thing; thus, the phrase is accurately translated as the Ten Sayings, the Ten Statements, the Ten Declarations, the Ten Words or even the Ten Things, but not as the Ten Commandments, which would be Aseret ha-Mitzvot. 
Judaism teaches that the first tablet, containing the first five declarations, identifies duties regarding our relationship with G-d, while the second tablet, containing the last five declarations, identifies duties regarding our relationship with other people.

Shavuot decorations - crochet flowers

For years, I never made the connection between the customary Shavuot decorations of flowers and any deeper feeling these decorations were supposed to engender.
As an agricultural holiday, Shavuot has always been linked to plant life. In particular, the baskets used to transport first fruits to the Temple were adorned with flowers and leaves. According to another explanation for the decorative scheme, the greens recall Sinai itself. The fact that the Israelites were warned not to allow their livestock to graze near the mountain (Shemot 19:12-13) indicates there was a grassy oasis at its base. The greens serve as vibrant reminders that Torah is “a tree of life to those who hold fast to it” (Proverbs 3:18).

The Omer - Shavuot, Hag ha'Bikkurim

An omer is a unit of measure. On the second day of Passover, in the days of the Temple, an omer of barley was cut down and brought to the Temple as an offering. This grain offering was referred to as the Omer.
