Numbers 17:3

And the LORD spake unto Moses, saying,

Speak unto the children of Israel, and take of every one of them a rod according to the house of their fathers, of all their princes according to the house of their fathers twelve rods: write thou every man's name upon his rod.

And thou shalt lay them up in the tabernacle of the congregation before the testimony, where I will meet with you.

And it shall come to pass, that the man's rod, whom I shall choose, shall blossom: and I will make to cease from me the murmurings of the children of Israel, whereby they murmur against you.
