Purim is distinctly a Jewish festival. Yet it gives us a wonderful picture of the Messiah our deliverer.
This was done on the thirteenth day of the month Adar, and on the fourteenth day they rested and made it a day of feasting and gladness… the Jews established and accepted a custom for themselves and for their seed and for all those who joined themselves to them, so that celebrating these two days according to what was written down and according to their fixed time from year to year would not pass away. So these days were to be remembered and celebrated throughout every generation, every family, every province and every city.
(Esther 9:17,27-28 LSB)
Then on the fifteenth day of the same month there is the Feast of Unleavened Bread to Yahweh; for seven days you shall eat unleavened bread. On the first day you shall have a holy convocation; you shall not do any laborious work. But for seven days you shall bring near an offering by fire to Yahweh. On the seventh day is a holy convocation; you shall not do any laborious work.
(Leviticus 23:6-8 LSB)
Then the LORD spoke to Moses, saying, “Speak to the sons of Israel and say to them, ‘When you enter the land which I am going to give to you and reap its harvest, then you shall bring in the sheaf of the first fruits of your harvest to the priest. He shall wave the sheaf before the LORD for you to be accepted; on the day after the sabbath the priest shall wave it. Now on the day when you wave the sheaf, you shall offer a male lamb one year old without defect for a burnt offering to the LORD. Its grain offering shall then be two-tenths of an ephah of fine flour mixed with oil, an offering by fire to the LORD for a soothing aroma, with its drink offering, a fourth of a hin of wine. Until this same day, until you have brought in the offering of your God, you shall eat neither bread nor roasted grain nor new growth. It is to be a perpetual statute throughout your generations in all your dwelling places.’” (Leviticus 23:9-14)
You shall also count for yourselves from the day after the sabbath, from the day when you brought in the sheaf of the wave offering; there shall be seven complete sabbaths. You shall count fifty days to the day after the seventh sabbath; then you shall present a new grain offering near to Yahweh. (Leviticus 23:15-16 LSB)
Three times a year you shall celebrate a feast to Me. You shall observe the Feast of Unleavened Bread; for seven days you are to eat unleavened bread, as I commanded you, at the appointed time in the month Abib, for in it you came out of Egypt. And none shall appear before Me empty-handed. Also you shall observe the Feast of the Harvest of the first fruits of your labors from what you sow in the field; also the Feast of the Ingathering at the end of the year when you gather in the fruit of your labors from the field. Three times a year all your males shall appear before the Lord GOD. (Exodus 23:14-17)
