The Feast Of Unleavened Bread is celebrated for seven days and the first and last days are Sabbaths. For this feast, we purge our homes of all leaven, symbolizing our purging of sin from our lives.
Leviticus 23:5-8 In the fourteenth day of the first month at even is the LORD'S passover.6 And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread.7 In the first day ye shall have an holy convocation: ye shall do no servile work therein.8 But ye shall offer an offering made by fire unto the LORD seven days: in the seventh day is an holy convocation: ye shall do no servile work therein.
Exodus 12:15-20 Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.16 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.17 And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever.18 In the first month, on the fourteenth day of the month at even, ye shall eat unleavened bread, until the one and twentieth day of the month at even.19 Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land.20 Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread.
1 Corinthians 5:7-8 Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us:
8 Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.
Luke 22:1 Now the feast of unleavened bread drew nigh, which is called the Passover.
HOW TO OBSERVE
Psalm 81: 3 Blow up the trumpet in the new moon, in the time appointed, on our solemn feast day.
Judges 5:11 They that are delivered from the noise of archers in the places of drawing water, there shall they rehearse the righteous acts of the LORD, even the righteous acts toward the inhabitants of his villages in Israel: then shall the people of the LORD go down to the gates.
CONGREGATING
Leviticus 23:3 Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; ye shall do no work therein: it is the sabbath of the LORD in all your dwellings
WITH GLADNESS
Numbers 10:10 Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, ye shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; that they may be to you for a memorial before your God: I am the LORD your God.
NO WORKING
Exodus 20:9-11 Six days shalt thou labour, and do all thy work: 10 But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: 11 For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it. Deuteronomy 5:14 But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy manservant, nor thy maidservant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that is within thy gates; that thy manservant and thy maidservant may rest as well as thou.
NO BUYING/SELLING
Nehemiah 10:31 And if the people of the land bring ware or any victuals on the sabbath day to sell, that we would not buy it of them on the sabbath, or on the holy day: and that we would leave the seventh year, and the exaction of every debt.
Nehemiah 13:15-21 In those days saw I in Judah some treading wine presses on the sabbath, and bringing in sheaves, and lading asses; as also wine, grapes, and figs, and all manner of burdens, which they brought into Jerusalem on the sabbath day: and I testified against them in the day wherein they sold victuals. 16 There dwelt men of Tyre also therein, which brought fish, and all manner of ware, and sold on the sabbath unto the children of Judah, and in Jerusalem. 17 Then I contended with the nobles of Judah, and said unto them, What evil thing is this that ye do, and profane the sabbath day? 18 Did not your fathers thus, and did not our God bring all this evil upon us, and upon this city? yet ye bring more wrath upon Israel by profaning the sabbath. 19 And it came to pass, that when the gates of Jerusalem began to be dark before the sabbath, I commanded that the gates should be shut, and charged that they should not be opened till after the sabbath: and some of my servants set I at the gates, that there should no burden be brought in on the sabbath day. 20 So the merchants and sellers of all kind of ware lodged without Jerusalem once or twice. 21 Then I testified against them, and said unto them, Why lodge ye about the wall? if ye do so again, I will lay hands on you. From that time forth came they no more on the sabbath.
NO CARRYING BURDENS
Jeremiah 17:21 Thus saith the Lord; Take heed to yourselves, and bear no burden on the sabbath day, nor bring it in by the gates of Jerusalem;
NO DOING YOUR OWN PLEASURE: NO SEX/PLAYING GAME/WATCHING FOOTBALL ETC
Isaiah 58:13-14 If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the Lord, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words: 14 Then shalt thou delight thyself in the Lord; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the Lord hath spoken it.
RESTING
Exodus 31:15-17 Six days may work be done; but in the seventh is the sabbath of rest, holy to the Lord: whosoever doeth any work in the sabbath day, he shall surely be put to death. 16 Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant. 17 It is a sign between me and the children of Israel for ever: for in six days the Lord made heaven and earth, and on the seventh day he rested, and was refreshed. Exodus 35: 2 Six days shall work be done, but on the seventh day there shall be to you an holy day, a sabbath of rest to the Lord: whosoever doeth work therein shall be put to death.
