After Israel's punishment, God cleanses a humbled remnant and converts it into a nation fit for the Millennium. National Israel's sins have piled up into a burden that weighs the nation down, so the punishment is a necessary beginning, but the process does not end there. Those who come out of the great tribulation, mourning and afflicted in soul, finally recognize that they pierced the Messiah, turn from their oppressors to depend on God in truth, and find grace in the wilderness. Zechariah 13:1 promises a fountain opened for sin and uncleanness, and Ezekiel 36:24-29 promises clean water, a new heart, and God's Spirit. God then redeems them, reunites Israel and Judah into one nation, and makes the New Covenant, writing His law on their hearts and remembering their sins no more. The Day of Atonement pictures this step. It has nothing to do with binding Satan and everything to do with God and His people being reconciled through forgiveness. Its three commands match the remnant's experience: afflicting the soul, holding a holy convocation to hear God's instruction, and doing no work, because only Christ's blood pays for sin. The two goats of Leviticus 16 are one sin offering with two aspects. The slain goat atones by blood, and the live goat of complete removal carries the confessed sins away into forgetfulness. Christ fulfills both by shedding His blood and bearing iniquity away (Isaiah 53; Hebrews 9). Cleansed and converted, the remnant becomes the human nucleus of His Kingdom and an example nation to the world.

God declares Israel and Judah unclean even after the return from Babylon, with a rebuilt altar, a consecrated priesthood, and a Temple under construction. Haggai's questions to the priests show that uncleanness is transferable while holiness is not, so even the Temple, its holy objects, and the Shekinah could not make the people clean. Under the Old Covenant, animal blood could only point to the perfect Sacrifice and could never remove sin. God's response on Kislev 24 is a blessing meant to bring them out of their condition, not reward it. That blessing is righteous leadership: Zerubbabel and Joshua are types of Jesus Christ, the ultimate Governor and High Priest, who will rule from a liberated and cleansed Jerusalem when God shakes heaven and earth and the Gentile kingdoms fall. Zechariah 3 foretells national cleansing by divine decree and the coming of the BRANCH, who will remove the land's iniquity in one day. Jeremiah 33 and Ezekiel 36 and 37 promise cleansing from all iniquity and idols, a new heart and spirit, an everlasting covenant of peace, and one reunited nation under one king, though Jacob's Trouble comes first. Those whom God has called already have this cleansing through Christ's sacrifice, baptism, a High Priest, and the Holy Spirit, and their lives are to testify to Israel and Judah of what God will do for them.

God has an appointed time to cleanse and restore Israel, set out in Daniel 9:24's seventy weeks, or 490 years, a span that also echoes Jesus' call to forgive seventy times seven. The prophecy is about God's forgiveness and restoration of His people, and it reaches completion when Christ returns. Six things are determined for Israel and Jerusalem. First, Christ ends rebellion (pesha, outright defiance of known law), removing the proud and leaving a humble, meek, truthful remnant, as Zephaniah 3 says. Second, He brings sin (chata, falling short) to completion by pouring out His Spirit on the whole house of Israel, old and young, as Joel 2 promises. Third, He makes reconciliation for iniquity (avon, stubborn stiff-neckedness). Kippa covers defilement and sin and heals the break between man and God, which is why Atonement precedes the Feast of Tabernacles. Israel is reconciled through Jesus' sacrifice, and Micah 7 says God casts all their sins into the sea. Fourth, everlasting righteousness goes out from Israel to all nations, taught by those in the first resurrection who serve as priests (Isaiah 2; Zechariah 8; Isaiah 30). Fifth, the prophetic vision is sealed as Jerusalem is again chosen for God's throne. Sixth, a Most Holy place is anointed, the sanctuary and temple in Jerusalem described in Ezekiel 43 and 45. In this way Israel is restored to the holy and righteous nation God intended from the beginning.

Preparing for the Feast of Tabernacles begins with understanding that God's rejoicing is not limited to happy, exuberant moments but includes the satisfaction He feels even when administering painful judgment for the sake of ultimate good, as seen in Deuteronomy 28 and 30. This foundation matters because rejoicing at the Feast is commanded as a choice and discipline, not merely a spontaneous emotional response, since the Hebrew word for rejoice suggests a momentary brightening tied to God or His ways rather than sustained happiness. A crucial preparatory principle is that the Feast does not occur in a vacuum. Amos 5 demonstrates that Israel's prosperity coexisted with moral corruption, and God rejected their feast days because their conduct throughout the year contaminated their worship. This shows that one's attitudes and behavior leading up to the Feast directly shape the experience at the Feast itself; one cannot separate daily conduct from festival observance. Personal reflection on a particularly unsatisfying Feast in 1974 illustrates this principle. Having no spiritual or physical responsibility, no arrangements to fellowship with others, and being consumed with personal interests like visiting family, sightseeing, and travel produced spiritual emptiness rather than rejoicing, despite pleasant physical circumstances. The lesson drawn is that the Feast is not a vacation, and self-focused attendance—giving nothing—results in leaving spiritually empty. Numbers 29 reveals that God required more sacrifices for the Feast of Tabernacles than for all other feasts combined, indicating that sacrifice—giving oneself at cost for others' benefit—is central to this Feast's meaning. Since sacrifice is the essence of love, and Deuteronomy 12 and 16 repeatedly link rejoicing with sacrificing before God in community with family, servants, Levites, strangers, orphans, and widows, true preparation involves cultivating a mindset of giving rather than self-gratification. Psalm 126 provides a symbolic picture: worshippers bringing sheaves represent sharing the fruit of labor and God's blessing with others. Preparation for the Feast, then, means bringing not only material offerings but spiritual fruit—the fruit of the Spirit described in Galatians 5, including love, joy, peace, and kindness—cultivated throughout the year, and deliberately sharing it with fellow worshippers through bearing one another's burdens, as instructed in Galatians 6. Ezekiel 36 extends this preparation into the Millennium itself, showing that God's cleansing and gift of a new heart require human cooperation to produce fruit; the Feast, as a small-scale picture of that future age, similarly demands the use of tools God has given to overcome inevitable problems with the right attitude rather than bitterness or self-pity. Since God commands rejoicing, this proves the attitude is subject to human will and must be actively produced, not passively expected. Ultimately, preparing for the Feast means resolving to imitate God's character of outgoing concern, giving, serving, and sacrificing, offering oneself in practical service, prayer, and generosity toward others, so that the Feast becomes a genuine demonstration of love for God rather than self-serving indulgence.
