The Feast of Pentecost lasted but one day. From the morrow after the sabbath—that is, from the second day of Unleavened Bread—the day that ye brought the sheaf of the wave offering; seven sabbaths, i.
e; weeks, were to be counted, making forty-nine days, and on the day following the completion of the seventh sabbath (meaning here the seventh week), the festival was to be held, whence its later name of Pentecost, or Fiftieth-day Feast.
It would have fallen about the beginning of June—a season of the year which would have made the journey to Jerusalem easy. The characteristic offering of the day was that of two wave loaves of two tenth deals … of fine flour … baken with leaven.
These loaves were regarded as the firstfruits unto the Lord of the wheat harvest, although the greater part of the crop had now been reaped and housed. They were to be leavened and brought out of your habitations; that is, they were to consist of such bread as was ordinarily used in daily life.
They were made out of ears of wheat selected and cut like the barley in the Feast of Unleavened Bread, and then threshed and ground in the temple court. Each loaf contained an omer of flour, amounting to about five pints, and would therefore have weighed about five pounds.
With these were offered two lambs, which were waved before the Lord by being led backwards and forwards before the tabernacle or the temple, and then the loaves were waved also, but they were not placed upon the altar, as they were leavened.
The twentieth verse, which is somewhat obscure in the Authorized Version, should be punctuated as follows. And the priest shall wave them (the two lambs) with the bread of the firstfruits (the two loaves) for a wave offering before the Lord; with the two lambs they (the loaves) shall be holy to the Lord for the priest.
The other sacrifices to be offered on this day are described in the text as seven lambs,… one young bullock, and two rams … for a burnt offering unto the Lord, with their meat offering, and their drink offerings,… and one kid of the goats for a sin offering.
In the Book of Numbers (Numbers 28:27) they are stated to be "seven lambs," "two young bullocks," "one ram," with meat and drink offerings, and "one kid of the goats." Seeing that in Leviticus one young bullock and two rams are commanded, and in Numbers "two young bullocks and one ram," it is reasonable to suppose that a copyist's error has found its way into one or the other text.
The feast was to be kept as a day of holy convocation, and no servile work was to be done upon it. The number of sacrifices offered by individuals who had come to Jerusalem caused the festivity to be in practice continued for several days subsequent to the festival itself.
