John Wesley on 1 Samuel 1:24

Three bullocks - One for a burnt - offering, the second for a sin - offering, and the third for a peace offering; all these sorts being expedient for this work and time. Flour - For the meal - offerings belonging to the principal sacrifices, which to each bullock were three tenth - deals, or three tenth parts of an ephah, and so nine parts of the ephah were spent, and the tenth part was given to the priest. Wine - For drink - offerings.
