A person designates all of his property as a dedication offering. Are his tefillin included?
Halachah 3: When a person consecrates or dedicates all his property, everything is taken — including his tefillin. This contrasts with arachim-collections where tefillin are left for the donor.
Question 2
A person says 'I consecrate what my fishing net brings up from the sea tomorrow.' Is this binding?
Halachot 26, 32–33: One cannot formally consecrate non-existent items, but pledging future produce creates a binding vow-obligation — as the Rambam derives from Jacob's vow at Bethel.
Question 3
A person consecrates half of his Canaanite servant as a dedication offering. What is the result?
Halachah 17: Consecrating half a servant creates joint ownership between the donor and the priests — the priestly portion becomes the private property of whatever priest receives it.
Question 4
A person says 'I consecrate myself.' What has he actually consecrated?
Halachah 20: One who consecrates himself has consecrated only his monetary worth — his market value as if sold as a servant. A person's body itself cannot become consecrated property.
Question 5
Is a consecration made in error (based on a mistaken assumption) binding?
Halachah 34: Just as a vow made in error is not binding, so too a consecration made under a mistaken assumption — e.g., 'when a black ox goes out, it will be consecrated,' and a white ox went out — is not binding.
