Contradiction with Deuteronomy 7:2
This verse instructs the Israelites to avoid making covenants with other nations, which contrasts with Isaiah 56:6 that speaks of foreigners joining themselves to serve the Lord.
Deuteronomy 7:2: And when the LORD thy God shall deliver them before thee; thou shalt smite them, [and] utterly destroy them; thou shalt make no covenant with them, nor shew mercy unto them:
Contradiction with Deuteronomy 23:1-3
These verses exclude certain groups, including foreigners, from entering the assembly of the Lord, while Isaiah 56:6 includes foreigners who follow the Lord.
Deuteronomy 23:1-3: He that is wounded in the stones, or hath his privy member cut off, shall not enter into the congregation of the LORD.
Contradiction with Nehemiah 13:1-3
This passage reinforces the exclusion of foreigners from the assembly, contradicting Isaiah 56:6 which welcomes them if they serve the Lord.
Nehemiah 13:1-3: On that day they read in the book of Moses in the audience of the people; and therein was found written, that the Ammonite and the Moabite should not come into the congregation of God for ever; [they...: Heb. there was read] [audience: Heb. ears]
Contradiction with Ezra 9:1-2
These verses describe the prohibition against intermarrying with people from other nations and imply separation from them, which contrasts with the inclusion of foreigners in Isaiah 56:6.
Ezra 9:1-2: Now when these things were done, the princes came to me, saying, The people of Israel, and the priests, and the Levites, have not separated themselves from the people of the lands, [doing] according to their abominations, [even] of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites.
Contradiction with Matthew 10:5
Jesus instructs his disciples to avoid the Gentiles, which contrasts with Isaiah 56:6's welcoming of non-Israelites who adhere to the covenant.
Matthew 10:5: These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into [any] city of the Samaritans enter ye not:
Paradox #1
Isaiah 56:6 talks about foreigners who choose to follow the Lord being included among His people. The potential inconsistency might be with Old Testament laws that seemed to separate Israelites from foreigners, highlighting a shift towards inclusivity in this verse. However, interpretations vary, and this is often seen as an evolution of understanding God's broader invitation to all.
Paradox #2
Isaiah 56:6 talks about foreigners joining themselves to the Lord to serve Him and keep His covenant. A possible contradiction or inconsistency might stem from the idea of inclusion versus exclusion. Some people might find it inconsistent that while this verse promotes inclusion of foreigners, other parts of the Bible contain laws that seem exclusive to Israelites or show hostility towards outsiders. This could create a tension between the message of universal acceptance and the specific rules for a chosen group.
