Three times thou shall keep a feast unto me in the year. The feast of the passover, on the fourteenth of the month Nisan or March; and the feast of weeks or pentecost fifty days after that; and the feast of tabernacles on the fifteenth day of Tisri or September.

The Fundamental Rights of Israel in its Religious and Theocratical Relation to Jehovah. - As the observance of the Sabbath and sabbatical year is not instituted in Exodus 23:10-12, so Exodus 23:14-19 do not contain either the original or earliest appointment of the feasts, or a complete law concerning the yearly feasts. They simply command the observance of three feasts during the year, and the appearance of the people three times in the year before the Lord; that is to say, the holding of three national assemblies to keep a feast before the Lord, or three annual pilgrimages to the sanctuary of Jehovah. The leading points are clearly set forth in Exodus 23:14 and Exodus 23:17, to which the other verses are subordinate. These leading points are משׁפּטים or rights, conferred upon the people of Israel in their relation to Jehovah; for keeping a feast to the Lord, and appearing before Him, were both of them privileges bestowed by Jehovah upon His covenant people. Even in itself the festal rejoicing was a blessing in the midst of this life of labour, toil, and trouble; but when accompanied with the right of appearing before the Lord their God and Redeemer, to whom they were indebted for everything they had and were, it was one that no other nation enjoyed. For though they had their joyous festivals, these festivals bore the same relation to those of Israel, as the dead and worthless gods of the heathen to the living and almighty God of Israel.

This is the first mention of the three great Yearly Festivals. The feast of Unleavened bread, in its connection with the Paschal Lamb, is spoken of in Exodus 12; Exodus 13:but the two others are here first named. The whole three are spoken of as if they were familiarly known to the people. The points that are especially enjoined are that every male Israelite should attend them at the sanctuary (compare Exodus 34:23), and that he should take with him an offering for Yahweh, presenting himself before his King with his tribute in his hand. That this condition belonged to all the feasts, though it is here stated only in regard to the Passover, cannot be doubted. See Deuteronomy 16:16.

23:14 The Passover, Pentecost, and feast of Tabernacles, in spring, summer, and autumn, were the three times appointed for their attendance; not in winter, because travelling was then uncomfortable; nor in the midst of their harvest.

14-18. Three times … keep a feast … in the year-This was the institution of the great religious festivals-"The feast of unleavened bread," or the passover-"the feast of harvest," or pentecost-"the feast of ingathering," or the feast of tabernacles, which was a memorial of the dwelling in booths in the wilderness, and which was observed in the seventh month (Ex 12:2). All the males were enjoined to repair to the tabernacle and afterwards the temple, and the women frequently went. The institution of this national custom was of the greatest importance in many ways: by keeping up a national sense of religion and a public uniformity in worship, by creating a bond of unity, and also by promoting internal commerce among the people. Though the absence of all the males at these three festivals left the country defenseless, a special promise was given of divine protection, and no incursion of enemies was ever permitted to happen on those occasions.
