These are the appointed times we are called to observe:
Passover – forever
14 ‘Now this day will be a memorial to you, and you shall keep it as an appointed time to Yahuwah throughout your generations you are to celebrate it as an ordinance forever.
15 Seven days you shall eat unleavened bread, but on the first day you shall remove the leaven from your houses [because it represents the spread of sin]; for whoever eats leavened bread on the first day through the seventh day, that person shall be cut off and excluded from [the atonement made for] YisraEl.
16 On the first day [of the appointed time] you shall have a holy and solemn assembly, and on the seventh day there shall be another holy and solemn assembly; no work of any kind shall be done on those days, except for the preparation of food which every person must eat—only that may be done by you.
17 You shall observe the appointed time of Unleavened Bread, because on this very day I brought your hosts [grouped according to tribal armies] out of the land of Egypt; therefore you shall observe this day throughout your generations as an ordinance forever.
18 In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread, [and continue] until the twenty-first day of the month at evening. 19 Seven days no leaven shall be found in your houses; whoever eats what is leavened shall be cut off and excluded from [the atonement made for] the congregation of YisraEl, whether a stranger or native-born.
20 You shall eat nothing leavened; in all your dwellings you shall eat unleavened bread.’”
21 Then Moses called for all the elders of YisraEl and said to them, “Go and take a lamb for yourselves according to [the size of] your families and slaughter the Passover lamb.
22 You shall take a bunch of hyssop, dip it in the blood which is in the basin, and touch some of the blood to the lintel [above the doorway] and to the two doorposts; and none of you shall go outside the door of his house until morning.
23 For the Yahuwah will pass through to strike the Egyptians; and when He sees the blood on the lintel [above the entry way] and on the two doorposts, Yahuwah will pass over the door and will not allow the destroyer to come into your houses to slay you. 24 You shall observe this event [concerning Passover] as an ordinance for you and for your children forever.
Appointed time of Unleavened bread, Appointed time of harvest, Appointed time of Ingathering – All males must attend.
14 “Three times a year you shall celebrate the appointed times with Me.
15 You shall observe the appointed time of Unleavened Bread; for seven days you shall eat unleavened bread, as I commanded you, at the appointed time in the month of Abib, for in it you came out of Egypt. No one shall appear before Me empty-handed.
16 Also [you shall observe] the Appointed time of Harvest (Weeks, Pentecost, or First Fruits), acknowledging the first fruits of your labor, of what you sow in the field.
And the appointed time of Ingathering (Booths or Tabernacles) at the end of the year when you gather in [the fruit of] your labours from the field. 17 Three times a year all your males shall appear before Yahuwah your Elohim.
Passover and the appointed time of unleavened bread.
1 “Observe the month of Abib and celebrate the Passover to Yahuwah your Elohim for in the month of AbibY ahuwah your Elohim brought you out of Egypt by night.
2 You shall sacrifice the Passover to Yahuwah your Elohim from the flock or the herd, in the place where Yahuwah chooses to establish His Name (Presence).
3 You shall not eat leavened bread with it; instead, for seven days you shall eat the Passover with unleavened bread, the bread of affliction (for you left the land of Egypt in haste); [do this] so that all the days of your life you may remember [thoughtfully] the day when you came out of the land of Egypt.
4 For seven days no leaven shall be seen with you in all your territory, and none of the meat which you sacrificed the evening of the first day shall remain overnight until morning.
5 You are not allowed to sacrifice the Passover [lamb] in any of your cities which Yahuwah your Elohim is giving you;
6 but at the place where Yahuwah your Elohim chooses to establish His Name (Presence), you shall sacrifice the Passover [lamb] in the evening at sunset, at the time that you came out of Egypt.
7 You shall cook and eat it in the place which Yahuwah your Elohim chooses. In the morning you are to return to your tents.
8 For six days you shall eat unleavened bread, and on the seventh day there shall be a celebration to Yahuwah your Elohim; so you shall do no work.
The appointed time of harvest
9 “You shall count seven weeks for yourself; you shall begin to count seven weeks from the time you first put the sickle to the standing grain. 10 Then you shall celebrate the Appointed time of Harvest to the Yahuwah your Elohim with a tribute of a freewill offering from your hand, which you shall give [to Him] just as Yahuwah your Elohim blesses you;
11 and you shall rejoice before Yahuwah your Elohim, you and your son and your daughter and your male and female servants and the Levite who is within your [city] gates, and the stranger and the orphan and the widow who are among you, at the place where the Yahuwah your Elohim chooses to establish His Name (Presence).
12 You shall remember that you were a slave in Egypt, and you shall be careful to obey these statutes.
The appointed time of ingathering
13 “You shall celebrate the appointed time of ingathering (Booths,Tabernacles) seven days, when you have gathered in [the grain] from your threshing floor and [the wine] from your wine vat.
14 You shall rejoice in your appointed time, you and your son and your daughter and your male and female servants and the Levite and the stranger and the orphan and the widow who are within your city.
15 Seven days you shall celebrate the appointed time to the Yahuwah your Elohim in the place which Yahuwah chooses, because Yahuwah your Elohim will bless you in all your produce and in all the work of your hands, so that you will be altogether joyful.
16 “Three times a year all your males shall appear before Yahuwah your Elohim in the place which He chooses, at the appointed time of Unleavened Bread and at the appointed time of Harvest (Pentecost) and at the Feast of ingathering (Booths, Tabernacles), and they shall not appear before Yahuwah empty-handed. 17 Every man shall give as he is able, in accordance with the blessing which Yahuwah your Elohim has given you.
The appointed time of atonement
29 “This shall be a permanent statute for you: in the seventh month on the tenth day of the month you shall humble yourselves [by fasting] and not do any work, whether the native-born or the stranger who lives temporarily among you;
30 for it is on this day that atonement shall be made for you, to cleanse you; you will be clean from all your sins before Yahuwah.
31 It is a Sabbath of solemn rest for you, and you shall humble yourselves; it is a permanent statute.
32 So the priest who is anointed and ordained to serve and minister as priest in his father’s place shall make atonement: he shall wear the holy linen garments,
33 and make atonement for the Holy Sanctuary, and he shall make atonement for the Tent of Meeting, and for the altar [of burnt offering in the court]. He shall also make atonement for the priests and for all the people of the assembly.
34 This shall be a permanent statute for you, so that atonement may be made for the children of Israel for all their sins once a year.” So he did just as Yahuwah had commanded Moses.
Who is Israel?
6 But it is not that the word of Yahuwah has taken no effect. For they are not all Israel whoare of Israel, 7 nor are they all children because they are the seed of Abraham; but, “In Isaac your seed shall be called.” 8 That is, those who are the children of the flesh, these are not the children of YHWH; but the children of the promise are counted as the seed.
26 For you are all children of Yahuwah through faith in Yahushua haMaschiach. 27 For all of you who were baptized into the Maschiach have clothed yourselves with the Maschiach. 28 There is [now no distinction in regard to salvation] neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you [who believe] are all one in Yahushua haMaschiach. 29 And if you belong to the Maschiach [if you are in Him], then you are Abraham’s descendants, and [spiritual] heirs according to the promise.
We don’t got to observe the scheduled worship times (MO-ey-DhIyM) we get to. It is amazing how the change of one vowel can be so transforming.
