Another important law revealed on this day referred to the celebration of "the second Passover feast." Mishael and Elzaphan, who had attended to the burial of Nadab and Abihu, were godly men, anxious to fulfil the commandments of God, hence they went to the house where Moses and Aaron instructed the people, and said to them: "We are defiled by the dead body of a man; wherefore are we kept back that we may not offer an offering of the Lord in His appointed season among the children of Israel?"
Moses at first answered that they might not keep the Passover owing to their condition of uncleanness, but they argued with him, asking that even if, owing to their condition, they might not partake of the sacrificial meat, they might, at least, be permitted to participate in the offering of the paschal lamb by having the blood of the offering sprinkled for them. Moses admitted that he could not pass judgement on this case before receiving instruction concerning it from God.
For Moses had the rare privilege of being certain of receiving revelations from God whenever he applied to Him. He therefore bade Mishael and Elzaphan await God's judgement concerning their case, and sentence was indeed revealed immediately.
