Numbers 6:7
He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die: because the consecration of his God is upon his head.
Cross-reference
Numbers 9:6 shows uncleanness from a dead body preventing Passover — reinforcing the severity of the Nazirite's absolute avoidance of corpse impurity even for family.
Leviticus 21:1 forbids priests from defiling themselves for the dead, paralleling the Nazirite's similar restriction against contact with corpses.
Leviticus 21:2 allows priests to become unclean for close relatives, contrasting with the Nazirite who cannot defile himself even for family.
In Leviticus 21:10-12, this same prohibition against defiling for deceased parents applies to the high priest, reinforcing the higher standard of consecration.
In Leviticus 21:11, the high priest is explicitly forbidden defilement for father or mother — nearly identical to the Nazarite's rule.
In Leviticus 10:6, Aaron and his sons are forbidden to mourn for the dead (his sons) due to anointing — similar to the Nazarite's restriction for parents.
In Ezekiel 44:25, priests may defile for immediate family, contrasting with the Nazarite's absolute prohibition — a stricter separation.
In Matthew 8:21, Jesus prioritizes following him over burying one's father — echoing the Nazarite's priority of God over family ties.
