Numbers 5:3 instructs removing the unclean from camp to prevent defilement; here, the same concern for contagion extends to objects — both safeguard the camp's purity.

Haggai 2:13 directly applies Numbers 19:22's principle—uncleanness from a dead body transfers by touch—confirming its ongoing force.

Leviticus 11:25 requires washing and uncleanness until evening for carrying a dead carcass—a parallel rule of contamination through contact.

In Leviticus 14:46, the same principle of uncleanness until evening applies to entering a contaminated house — both laws define transmission of ritual impurity.

Leviticus 7:19 applies the same principle: meat touching something unclean becomes unfit, echoing that the unclean person's touch contaminates.

Leviticus 15:5 shows the same pattern: touching a contaminated bed requires washing and uncleanness until evening, matching the transfer principle.
