The shtei halechem are subject to me’ilah from when they are consecrated. [Once] they crust in the oven, they become prepared to be disqualified through [contact with] a tevul yom or through [contact with] a mechussar kippurim, and [they become fit] to slaughter the [shelamim-] offering on account of them. [Once] the blood of the lambs is sprinkled [upon the Altar], one is liable on account of [the shtei halechem] for piggul, nossar, or tamei, and they are no longer subject to me’ilah.
