sanctify

Both derive from the Hebrew root q-d-sh (to be set apart) — the verb qiddesh (to sanctify) and the noun miqdash (sanctuary/holy place) are the same root concept in different aspects.

Atonement cleanses the sinner; sanctification sets apart the cleansed for God's use. In Leviticus, atonement and sanctification are sequential movements in the same priestly logic.

Hebrew qiddush (consecration) and qiddesh (to sanctify) derive from the same root q-d-sh — consecration is the completed act; sanctify is the ongoing process. Both describe the same movement toward holiness.
