“At His right hand was a fiery law unto them.”
– Deuteronomy 33:2, JPS 1917 Tanach
On Simchas Torah, the entire portion of V’zot HaBeracha is read; this is the last parashas of the Torah. Afterwards, the first part of Bereishis, the first parashas of the Torah is read, in order to make the statement that we begin anew, immediately following an ending. This reminds of the saying, when one door closes, another door opens, meaning that when one endeavor is brought to its conclusion, another opportunity will prevail. The seasons of nature, as well as the seasons of our lives reflect this theme.
Within the framework of the parashas, B’nei Yisrael is poised to enter Eretz Canaan; Moshe is intent on imparting a berachah (blessing) to them. This blessing parallels the blessing that Jacob gave to his twelve sons; inasmuch that Moshe has been the king and prophet over B’nei Yisrael, he is giving a blessing to the twelve tribes.
Moshe begins, “The L-RD came from Sinai,” therefore, emphasizing H’Shem’s presence, of Whom “at His right hand was a fiery law unto them” (Deuteronomy 33:2, JPS). “The voice of the L-RD heweth out flames of fire” (Psalm 29:7, JPS). H’Shem’s voice appeared as fire that engraved the commandments into the two stone tablets. On Simchat Torah, may we rejoice in acknowledgment of H’Shem’s promise through the prophet, to engrave these words on our heart in due time:
“This is the covenant that I will make with the house of Israel after those days, saith the L-RD, I will put My law in their inward parts, and in their heart will I write it; and I will be their G-d, and they shall be My people.”
– Jeremiah 31:33, JPS 1917 Tanach
