Contradiction with 1 Samuel 8:1
This verse notes that Samuel made his sons judges over Israel, which contradicts the centralized religious authority under the Levites as mentioned in 1 Chronicles 23:27.
1 Samuel 8:1: And it came to pass, when Samuel was old, that he made his sons judges over Israel.
Contradiction with Numbers 4:3

Numbers 4:3: From thirty years old and upward even until fifty years old, all that enter into the host, to do the work in the tabernacle of the congregation.
Contradiction with Numbers 8:24
This verse states that Levites begin their service at age 25, creating confusion compared to the age of 20 in 1 Chronicles 23:27.
Numbers 8:24: This [is it] that [belongeth] unto the Levites: from twenty and five years old and upward they shall go in to wait upon the service of the tabernacle of the congregation: [to...: Heb. to war the warfare of, etc]
Paradox #1
1 Chronicles 23:27 is part of administrative details regarding the duties of the Levites in the temple. A potential contradiction or inconsistency might arise if one questions why certain religious roles or duties are divinely assigned exclusively to certain groups or tribes, such as the Levites, which might seem like favoritism or discrimination when viewed through a modern lens advocating for equality and inclusivity. However, this is often understood within the historical and cultural context of the times.
