Feast of Atonement; Jubilee?
Leviticus 25:8-10  And thou shalt number seven sabbaths of years unto thee, seven times seven years; and the space of the seven sabbaths of years shall be unto thee forty and nine years. 9Then shalt thou cause the trumpet of the jubilee to sound on the tenth day of the seventh month, in the day of atonement shall ye make the trumpet sound throughout all your land.  10And ye shall hallow the fiftieth year, and proclaim liberty throughout all the land unto all the inhabitants thereof: it shall be a jubilee unto you; and ye shall return every man unto his possession, and ye shall return every man unto his family.
In That Day
I John 3:1-3 1Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not. 2Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. 3And every man that hath this hope in him purifieth himself, even as he is pure.
Hebrews 10:25 Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting (3870 beseech, comfort) one another: and so much the more, as ye see the day approaching. READ Joshua 4:19-24
Philippians 1:6 Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:
Joel 2:15-16 Blow the trumpet in Zion, sanctify a fast, call a solemn assembly: 16Gather the people, sanctify the congregation, assemble the elders, gather the children, and those that suck the breasts: let the bridegroom go forth of his chamber, and the bride out of her closet.
Amos 8:1-3 Thus hath Yahuweh who saves GOD shewed unto me: and behold a basket of summer fruit. 2And he said, Amos, what seest thou? And I said, A basket of summer fruit. Then said Yahuweh unto me, The end is come upon my people of Israel; I will not again pass by them any more.
Judgment is now, God will no longer pass by sin it will be dealt with.
3And the songs of the temple shall be howlings in that day, saith Yahuweh who saves GOD: there shall be many dead bodies in every place; they shall cast them forth with silence.                          Yahushua explains when and why!
. Amos 8:9-14 And it shall come to pass in that day, saith the Yahuweh who saves GOD, that I will cause the sun to go down at noon, and I will darken the earth in the clear day: 10And I will turn your feasts into mourning, and all your songs into lamentation; and I will bring up sackcloth upon all loins, and baldness upon every head; and I will make it as the mourning of an only son, and the end thereof as a bitter day.
11Behold, the days come, saith Yahuweh who saves GOD, that I will send a famine in the land, not a famine of bread, nor a thirst for water, but of hearing the words of Yahuweh: 12And they shall wander from sea to sea, and from the north even to the east, they shall run to and fro to seek the word of Yahuweh, and shall not find it. 13In that day shall the fair virgins and young men faint for thirst. 14They that swear by the sin of Samaria, and say, Thy god, O Dan, liveth; and, The manner of Beersheba liveth; even they shall fall, and never rise up again. 
Father thank You for understanding and knowledge as we search Your word for truth, Halle lu YAH
