Contradiction with Numbers 36:6
This verse contradicts with Numbers 36:1 as it provides a specific solution about marriage restrictions for the daughters of Zelophehad which can be seen to limit their freedom, whereas Numbers 36:1 is about addressing inheritance questions.
Numbers 36:6: This [is] the thing which the LORD doth command concerning the daughters of Zelophehad, saying, Let them marry to whom they think best; only to the family of the tribe of their father shall they marry. [marry: Heb. be wives]
Contradiction with Galatians 3:28

Galatians 3:28: There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
Contradiction with 1 Corinthians 7:39
This verse allows widows to marry whom they wish, seemingly contradicting Numbers 36:1's context where marriage is restricted to maintain inheritance within the tribe.
1 Corinthians 7:39: The wife is bound by the law as long as her husband liveth; but if her husband be dead, she is at liberty to be married to whom she will; only in the Lord.
Contradiction with Romans 10:12
This verse states there is no difference between Jew and Greek, contrasting with the tribal distinctions implied in Numbers 36:1.
Romans 10:12: For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
