Following the procedure G-d prescribed (Numbers 8:5-22), Moses inducted the Levites into Tabernacle service. The induction ceremony included sprinkling them with the ashes of the Red Heifer which was prepared the day beforehand.

In today's "Nasi" reading (see "Nasi of the Day" in Nissan 1), we read of the gift bought by the nasi of the tribe of Zebulun, Eliav ben Cheilon, for the inauguration of the Mishkan.
How to unmask a blessing in disguise:
Stare it in the face and say, “I know you are not just a lousy day or bad luck. I know you are a good friend—even if for the life of me I cannot determine how. I know there is only one Source of All Things, and nothing can convince me that evil descends from Above. Evil descends from the constraints of my perception. You are no more than a blessing in disguise.”
This blessing, if truly a great one, will not surrender its cover easily. You will need a composure that demonstrates you meant every word you said. You will need to hold your ground like a mountain against the sea. You will need to surprise yourself with your own resolve.
And then you can turn over a world. A world that once distorted every blessing that squeezed through its gates will now open those gates wide. And the blessings that have already entered will sigh a breath of relief as one by one they discard their scary costumes.
