Flavius Josephus, Antiquities of the Jews
William Whiston, A.M., Ed.

[233] Now the law requires, both in private and public sacrifices, that the finest flour be also brought; for a lamb the measure of one tenth deal, - for a ram two, - and for a bull three. This they consecrate upon the altar, when it is mingled with oil; for oil is also brought by those that sacrifice; for a bull the half of an hin, and for a ram the third part of the same measure, and one quarter of it for a lamb. This hin is an ancient Hebrew measure, and is equivalent to two Athenian choas (or congiuses). They bring the same quantity of oil which they do of wine, and they pour the wine about the altar; but if any one does not offer a complete sacrifice of animals, but brings fine flour only for a vow, he throws a handful upon the altar as its first-fruits, while the priests take the rest for their food, either boiled or mingled with oil, but made into cakes of bread. But whatsoever it be that a priest himself offers, it must of necessity be all burnt. Now the law forbids us to sacrifice any animal at the same time with its dam; and, in other cases, not till the eighth day after its birth. Other sacrifices there are also appointed for escaping distempers, or for other occasions, in which meat-offerings are consumed, together with the animals that are sacrificed; of which it is not lawful to leave any part till the next day, only the priests are to take their own share.
