“A man who is clean shall gather up the ashes of the heifer, and lay them up outside of the camp in a clean place; and it shall be kept for the congregation of the children of Israel for use in water for cleansing impurity. It is a sin offering.

Allusion1
A deliberate verbal borrowing without a citation formula.
‘The ashes of a heifer sprinkling those who have been defiled’ (v. 13) names the red-heifer rite of Num 19:9. Strong verbal volume (‘ashes of the heifer… cleansing impurity’) and exact thematic coherence: an outward cleansing ‘of the flesh’ that Hebrews contrasts with the inward cleansing of conscience by Christ's blood.
High confidenceEcho2
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
The 'water of purification' from the red heifer informs the cleansing connotation of 'the water' among the witnesses. Purifying water and atoning blood together echo the Pentateuchal rites of cleansing. The pairing of water and blood recalls Israel's purification system.
Low confidenceThe ‘water for cleansing impurity’ of the red-heifer rite (invoked explicitly at 9:13) lingers behind ‘body washed with pure water.’ Faint and contested as a distinct source here, but Hebrews has already paired heifer-ashes with sprinkling, so the recurrence keeps the lustration imagery in play.
