Leviticus 27:32-33 - Exposition

The tithe of the cattle could neither be vowed nor redeemed. As the young oxen and sheep passed under the rod by which they were counted by the herdsman, the tenth animal was touched (the rod, according to tradition, having been dipped in red paint), and handed over to the Levites. There was to be no change made in the animals, nor was commutation allowed.
