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.
Yahweh, via Ezekiel, wanted them to purify the sanctuary on the 1st day of the 1st month. In other words, this would be a New Year’s Day activity. They were to take an unblemished bull and use him to cleanse the sanctuary at the start of the new year. The priest should take some of the blood from the sin offering and put it on the doorposts of the Temple, as well as the four corners of the altar ledge and the posts of the gate of the inner court. The priest was also supposed to do this same ritual on the 7th day of the month for anyone who sinned inadvertently by error or ignorance. This purification ritual of the first day of the first month of the year would make an atonement for the Temple, so that it would be purified.
After the first day of consecrating the altar, the following day they were to offer an unblemished male goat as a sin offering. However, the altar had to be purified as it had been the previous day. Then, they were to offer another unblemished bull, as well as an unblemished ram. These burnt offerings were to be offered to Yahweh. The priests should sprinkle salt on them, before they were offered up to Yahweh.
