2,985. Sanctifying a Fit Kosher Animal for Temple Upkeep
Hilchos Arachin Vacharamin 5:4
Let’s say that someone other than the owner redeemed a consecrated house from the Temple. If the house was in a walled city and it was possessed for 12 months by the one who redeemed it, it becomes his permanent property. If the house was outside, in an unwalled area, and yoveil arrived while it was in the redeemer’s possession, it goes back to the original owner in yoveil.
Hilchos Arachin Vacharamin 5:5
If someone consecrates an unblemished kosher animal for Temple upkeep, even though he has acted counter to a Torah obligation (as we will see in the next halacha), his actions are effective. The animal is sanctified and it can be redeemed even though it’s unblemished. The kohein appraises its value and the money for it is used for Temple upkeep. The one who redeems it may only redeem it for offering on the altar as an appropriate sacrifice. This is because anything consecrated that may be offered on the altar is never released from the altar.
