Numbers 17:1-5 (KJV)
1 And the Lord spake unto Moses, saying,
2 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.
3 And thou shalt write Aaron’s name upon the rod of Levi: for one rod shall be for the head of the house of their fathers.
4 And thou shalt lay them up in the tabernacle of the congregation before the testimony, where I will meet with you.
5 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.
