Yahweh continues telling Moses what the priests must do.

on whose head the anointing oil has been poured, and who has been consecrated

AT: "on whose head they poured anointing oil and consecrated him" (See: rc://en/ta/man/translate/figs-activepassive)

must not wear his hair loose or tear his clothes

These are signs of mourning. (See: rc://en/ta/man/translate/figs-explicit)

must not leave the sanctuary area

This does not mean he could never leave. God did not allow him to leave in order to grieve over someone who has died.
