VIN⁽ⁱ⁾ ¹⁵ "'You shall count from the next day after the Sabbath, from the day that you brought the sheaf of the wave offering; seven Sabbaths shall be completed: ¹⁶ You will number fifty days, even to the morrow after the seventh Sabbath and you will offer a new meal offering to the LORD. ¹⁷ Out of your dwellings shall ye bring two wave-loaves, of two tenths of fine flour; with leaven shall they be baken; [as] first-fruits to the LORD. ¹⁸ You shall present with the bread seven lambs without blemish a year old, one young bull, and two rams. They shall be a burnt offering to the LORD, with their grain offering, and their drink offerings, even an offering made by fire, of a sweet aroma to the LORD. ¹⁹ You shall offer one male goat for a sin offering, and two male lambs a year old for a sacrifice of peace offerings. ²⁰ The priest shall wave them with the bread of the first fruits for a wave offering before the LORD, with the two lambs. They shall be holy to the LORD for the priest. ²¹ "'Do none of your daily work. Gather for worship. Your descendants are to observe this regulation from generation to generation, no matter where they live.
