15 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.
Chag ha’Matzot – is a Perpetual memorial feast that reminds us of several things. First, because Yahweh brought us out of Egypt, too, and at the same time it is a memorial that Yeshua rescued us, once and for all, from the condemnation of sin; and it is also a feast in which we keep in mind that one day we will be called by Yahweh, in a second Exodus, but this time from all the nations to gather us and bring us to the land of Israel, as it says in the prophets (Hosea 11:10; Jeremiah 23:3-7; Ezekiel 36: 24).
And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.
