(15) Ye shall count . . . from the morrow after the sabbath.--That is, from the day following the first day of holy convocation, which was a rest day. As this was the fifteenth of Nisan, the counting began from the sixteenth (see Leviticus 23:11), the day on which the omer of the first-fruits was presented to the Lord.

Seven sabbaths shall be complete.--Better, seven weeks shall be complete. That is, seven entire weeks, making forty-nine days. The expression sabbath denotes here a week, hence the parallel passage substitutes the word week, viz., "seven weeks shalt thou number unto thee" (Deuteronomy 16:9), The same usage is to be found in the New Testament. Thus the passage rendered in the Authorised version, "the first day of the week," is "the first day of the sabbath" (Matthew 28:1); and "I fast twice in the week" (Luke 18:12), is, "I fast twice in the sabbath." In accordance with the injunction here given, the Jews to the present day begin to count the forty-nine days at the conclusion of the evening service on the second day of Passover, and pronounce the following blessing every evening of the forty-nine days: "Blessed art thou, O Lord our God, King of the universe, who hast sanctified us with thy commandments, and hast enjoined us to count the omer. This is the first day of the omer. May it please thee, O Lord our God, and the God of our fathers, to rebuild the sanctuary speedily in our days, and give us our portion in thy Law.

Verses 15-21. - 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.

23:15-22 The feast of Weeks was held in remembrance of the giving of the law, fifty days after the departure from Egypt; and looked forward to the outpouring of the Holy Ghost, fifty days after Christ our Passover was sacrificed for us. On that day the apostles presented the first-fruits of the Christian church to God. To the institution of the feast of Pentecost, is added a repetition of that law, by which they were required to leave the gleanings of their fields. Those who are truly sensible of the mercy they received from God, will show mercy to the poor without grudging.And ye shall count unto you from the morrow after the sabbath,.... Not the seventh day sabbath in the passover week, nor the whole feast of unleavened bread, but the first day of it, which was an holy convocation, a sabbath in which no servile work was to be done, Leviticus 23:7; and it was from the day after this, even the sixteenth of Nisan, that the following count was to be made; so the Targum of Jonathan, after the first feast day of the passover: and Josephus (s) is very clear in it, that Pentecost, or the feast of weeks, was the fiftieth day from the sixteenth of Nisan, when the above offerings were made:

from the day that ye brought the sheaf of the wave offering; which plainly points out the express day from whence the count was to begin, even on the day when the sheaf of the firstfruits of the barley harvest was offered:

seven sabbaths shall be complete; or seven weeks, that is, forty nine days; and hence, Jarchi says, we learn that the count began from the evening, or otherwise the weeks would not be complete; and Gersom thinks the day in which the sheaf was offered is included in the days counted; for the count began from the day after the first of the passover, and lo, seven days are seven weeks of days, which make forty nine days.
