Romans 9:29 in the King James Version of the Bible states: "And as Esaias said before, Except the Lord of Sabaoth had left us a seed, we had been as Sodoma, and been made like unto Gomorrha."

This verse is part of the larger passage in Romans 9 where the apostle Paul is discussing the sovereignty of God and His plan for Israel. In the preceding verses, Paul talks about how not all of Israel is truly part of Israel, and that God has the right to show mercy to whomever He chooses. In verse 29, he quotes from the prophet Isaiah (Esaias) to illustrate this point.

The first part of the verse, "Except the Lord of Sabaoth had left us a seed," refers to the fact that God had preserved a remnant of faithful Israelites. The term "Lord of Sabaoth" is a Greek transliteration of the Hebrew phrase "Yahweh Sabaoth," which means "the Lord of Hosts" or "the Lord of Armies." This title emphasizes God's power and authority over all creation, as well as His role as the leader of the heavenly armies. By using this title, Paul is highlighting the fact that it is God's intervention alone that has preserved a remnant of Israel.

The second part of the verse, "we had been as Sodoma, and been made like unto Gomorrha," refers to the fate that Israel would have suffered if God had not preserved a remnant. Sodom and Gomorrah were cities in the Old Testament that were known for their wickedness and sinfulness. In the book of Genesis, God destroyed these cities with fire and brimstone because of their extreme wickedness. By comparing Israel to Sodom and Gomorrah, Paul is emphasizing the severity of the judgment that would have befallen Israel if God had not intervened to preserve a remnant.

The broader context of this verse is important for understanding its significance. Throughout the book of Romans, Paul is addressing the relationship between the Jewish people and the gospel of Jesus Christ. He is explaining that not all ethnic Jews are part of true Israel, and that God's plan for salvation extends to both Jews and Gentiles. In this specific passage, Paul is highlighting the fact that God's sovereign choice plays a crucial role in the salvation of individuals. He is emphasizing that it is not by works or by lineage that one is chosen by God, but by His mercy alone.

In terms of themes, this verse speaks to the themes of God's sovereignty, His role as the preserver of a faithful remnant, and the severity of judgment for those who reject Him. It also speaks to the broader theme of the inclusion of Gentiles in God's plan of salvation, as Paul is demonstrating that God's mercy extends beyond ethnic boundaries.

Symbolically, the quote from Isaiah and the comparison to Sodom and Gomorrah serve as a reminder of God's judgment and mercy. It serves as a warning that those who choose to reject God and His mercy will face severe consequences, but also as a reminder that God's mercy is available to all who repent and turn to Him.

In conclusion, Romans 9:29 is a powerful verse that emphasizes God's sovereignty, His role as the preserver of a faithful remnant, and the severity of judgment for those who reject Him. It also speaks to the broader theme of the inclusion of Gentiles in God's plan of salvation, and serves as a symbolic reminder of God's judgment and mercy.
