וַיִּזְבְּח֣וּ לַיהוָ֣ה ׀ זְ֠בָחִים וַיַּעֲל֨וּ עֹל֜וֹת לַיהוָ֗ה לְֽמָחֳרַת֮ הַיּ֣וֹם הַהוּא֒ פָּרִ֨ים אֶ֜לֶף אֵילִ֥ים אֶ֛לֶף כְּבָשִׂ֥ים אֶ֖לֶף וְנִסְכֵּיהֶ֑ם וּזְבָחִ֥ים לָרֹ֖ב לְכָל־יִשְׂרָאֵֽל׃
이튿날 여호와께 제사를 드리고 또 번제를 드리니 수송아지가 일천이요 수양이 일천이요 어린 양이 일천이요 또 그 전제라 온 이스라엘을 위하여 풍성한 제물을 드리고
Ramban
The meaning of the expression and they drank, is that they made it an occasion for rejoicing and festival, for such is one’s duty to rejoice at the receiving of the Torah, just as He commanded when they finished writing all the words of the Torah upon the stones, And thou shalt sacrifice peace-offerings, and shalt eat there; and thou shalt rejoice before the Eternal thy G-d.545Deuteronomy 27:7. And with reference to Solomon it is written, Wisdom and knowledge is granted unto thee etc.,546II Chronicles 1:12. and immediately after that, he came to Jerusalem… and made a feast for all his servants.547I Kings 3:15. “Said Rabbi Eleazar:548Shir Hashirim Rabbah 1:9. From here you learn that we make a feast at the finishing of the Torah.” With reference to David, Solomon’s father, it is likewise said that when the people gave of their free-will towards the building of the Sanctuary, And they offered sacrifices unto the Eternal, and offered burnt-offerings unto the Eternal etc., and they did eat and drink before the Eternal on that day with great gladness.549I Chronicles 29:21-22. Similarly, here too on the day of the “wedding” of the Torah,550Taanith 26b. they did likewise.
