Contradiction with Numbers 18:7
This verse designates only the priests, Aaron and his descendants, as those who shall perform duties related to the altar and within the veil, while 2 Chronicles 23:6 allows non-priests to enter into the house of the Lord.
Numbers 18:7: Therefore thou and thy sons with thee shall keep your priest's office for every thing of the altar, and within the vail; and ye shall serve: I have given your priest's office [unto you] as a service of gift: and the stranger that cometh nigh shall be put to death.
Contradiction with 2 Chronicles 26:16-21
Uzziah's attempt to enter the temple and burn incense, an act reserved for priests alone, contradicts the allowance in 2 Chronicles 23:6, resulting in his leprosy.
2 Chronicles 26:16-21: But when he was strong, his heart was lifted up to [his] destruction: for he transgressed against the LORD his God, and went into the temple of the LORD to burn incense upon the altar of incense.
Contradiction with Nehemiah 13:1
This verse recalls the exclusion of foreign elements from the congregation, contradicting the more inclusive allowance in 2 Chronicles 23:6.
Nehemiah 13:1: 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 Ezekiel 44:9
This verse restricts foreigners and those uncircumcised in heart or flesh from entering, contradicting the more lenient access seen in 2 Chronicles 23:6.
Ezekiel 44:9: Thus saith the Lord GOD; No stranger, uncircumcised in heart, nor uncircumcised in flesh, shall enter into my sanctuary, of any stranger that [is] among the children of Israel.
Paradox #1
The contradiction or inconsistency in this verse might involve the concept of exclusion based on religious or ritual purity. It suggests that only certain people are allowed in a holy place, which could conflict with modern ideas of inclusivity and equal access to religious spaces. Some may see this as inconsistent with the idea that everyone should have the same opportunity to worship and connect with the divine.
