At all the religious festivals, a grain offering of an ephah (2/3rds of a bushel) would accompany the young bull or the ram. However, as stated earlier, the prince could provide as much grain as he wanted to for the sacrifice of the lambs. However, with every ephah of grain, there had to be a gallon or hin of oil. It seems that the animals were cooked in oil with grains.
Besides the Sabbath, the other regular festival was the monthly new moon sacrifice. The lunar calendar was based on the 28-day cycle of the moon. Once again, the prince was responsible for furnishing the animals and the grain offerings, as on the Sabbath. He was to take an unblemished bull with 6 lambs and an unblemished ram for the burnt offerings. He was to offer them up with a grain offering. He too had to provide an ephah of grain (2/3rds of a bushel) with the bull and the ram. However, this prince could decide how much grain went with the lambs, but there had to be a gallon or hin of oil for each ephah of grain. The prince would enter and leave at the same gate.
