Bekhorot 5: Wilderness Accounting

Rabbi Yochanan came to Rabbi Elazar in a dream, and it was a harbinger for a good day. And the sanctification of the first-borns would not end, because of his own learning. Also, the story of a Roman official (Kunterukus) who bothers Rabbi Yochanan ben Zakkai about the number of Levites in the wilderness and in the final count in the Torah. Also, on the census count of the half-shekel. Where there shenanigans in the census money? Poor accounting? Plus, a new mishnah: A cow that gives birth to a kind of donkey... The question is when the first-born law kicks in, but the other question is how does a cow deliver a kind of donkey? Even given the exceptional status of the donkey.
