Referência sobre Êxodo 19:1

The fiftieth day of the count of the Omer is the holiday of Shavuot. The prayer service is like the holiday of Passover, rather we say "the Holiday of Shavuot, the time of the giving of our Torah". We say full Hallel. We take out two Torah scrolls and read in the first one of five [sections] from "The third month" until the end of the order. The Maftir is read in the second scroll, "On the day of the first fruits". As Haftorah we read the chariot of Ezekiel, and end with the verse "and the wind took me up."
