 Josephus uses the term both for Abraham and Isaac, but also, more surprisingly in relation to the human sacrifice by Ahaz of his son to Baal.The practice is also referenced by Philo, but with significant changes.Chazal sources, 3rd-6th Century CE, portray the "olah" form of sacrifice, in which no meat was left over for consumption by the Kohanim, as the greatest form of sacrifice and was the form of sacrifice permitted by Judaism to be sacrificed at the Temple by the Kohanim on behalf of both Jews and non-Jews.
