The passover takes its name from the fact that the angel of the Lord passed over the houses of the Hebrews on that eventful night when the firstborn in every Egyptian family was slain. This feast was ordained in commemoration of the deliverance of that people from Egyptian bondage. It began with the slaying of the paschal lamb on the fourteenth day of the first month, and extended through a period of seven days, in which nothing but unleavened bread was to be eaten. Its great antitype was reached when Christ our passover was sacrificed for us.[164] The Pentecost was the second of the Jewish feasts, and occupied but a single day. It was celebrated on the fiftieth day after the first-fruits of barley harvest had been waved before the Lord. At the time of this feast the first-fruits of wheat harvest were offered unto God. The antitype of this festival was reached on the fiftieth day after the resurrection of Christ, when the great outpouring of the Holy Ghost took place.[165] The feast of tabernacles was the last of the Jewish feasts. It was celebrated in the seventh month when they had gathered in the fruit of the land, and extended from the fifteenth to the twenty-first day of that month. It was ordained as a festival of rejoicing before the Lord; and during this period the children of Israel dwelt in booths in commemoration of their dwelling thus during their sojourn in the wilderness. It probably typifies the great rejoicing after the final gathering of all the people of God into his kingdom.[166] In connection with these feasts it was ordained that each new moon, that is, the first day of every month, should be observed with certain specified offerings, and with tokens of rejoicing.[167] The annual sabbaths of the Hebrews have been already enumerated. The first two of these sabbaths were the first and seventh days of the feast of unleavened bread, that is, the fifteenth and twenty-first days of the first month. They were thus ordained by God:— “Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses.... And in the first day there shall be an holy convocation, and in the seventh day there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that only may be done of you.”[168] The third in order of the annual sabbaths was the day of Pentecost. This festival was ordained as a rest-day in the following language:— “And ye shall proclaim on the selfsame day, that it may be an holy convocation unto you: ye shall do no servile work therein; it shall be a statute forever in all your dwellings throughout your generations.”[169] The first day of the seventh month was the fourth annual sabbath of the Hebrews. It was thus ordained:—
