And those that were numbered of the families of the sons of Merari, throughout their families, by the house of their fathers,

From thirty years old and upward even unto fifty years old, every one that entereth into the service, for the work in the tabernacle of the congregation,

Even those that were numbered of them after their families, were three thousand and two hundred.

These be those that were numbered of the families of the sons of Merari, whom Moses and Aaron numbered according to the word of the LORD by the hand of Moses.

From thirty years old and upward even unto fifty years old, every one that came to do the service of the ministry, and the service of the burden in the tabernacle of the congregation.

Even those that were numbered of them, were eight thousand and five hundred and fourscore,

According to the commandment of the LORD they were numbered by the hand of Moses, every one according to his service, and according to his burden: thus were they numbered of him, as the LORD commanded Moses.
