Old Testament

The Fourth Book of Moses Called Numbers: Chapter 4:29-34-37

"As for the sons of Merari, you shall number them by their families and by their fathers' house. From thirty years old and above, even to fifty years old, you shall number them, everyone who enters the service to do the work of the tabernacle of meeting. And this is what they must carry as all their service for the tabernacle of meeting: the boards of the tabernacle, its bars, its pillars, its sockets, and the pillars around the court with their sockets, pegs, and cords, with all their furnishings and all their service; and you shall assign to each man by name the items he must carry. This is the service of the families of the sons of Merari, as all their service for the tabernacle of meeting, under the authority of Ithamar the son of Aaron the priest."

And Moses, Aaron, and the leaders of the congregation numbered the sons of the Kohathites by their families and by their fathers' house, from thirty years old and above, even to fifty years old, everyone who entered the service for work in the tabernacle of meeting; and those who were numbered by their families were two thousand seven hundred and fifty. These were the ones who were numbered of the families of the Kohathites, all who might serve in the tabernacle of meeting, whom Moses and Aaron numbered according to the commandment of the Lord by the hand of Moses.

New Testament

The First Epistle of Peters: Chapter 2:1-4-10

Therefore, laying aside all malice, all deceit, hypocrisy, envy, and all evil speaking, as newborn babes, desire the pure milk of the word, that you may grow thereby, if indeed you have tasted that the Lord is gracious.

Coming to Him as to a living stone, rejected indeed by men, but chosen by God and precious, you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ. Therefore it is also contained in the Scripture,

"Behold, I lay in Zion A chief cornerstone, elect, precious,
And he who believes on Him will by no means be put to shame."

Therefore, to you who believe, He is precious; but to those who are disobedient,

"The stone which the builders rejected
Has become the chief cornerstone,"

and

"A stone of stumbling
And a rock of offense."

They stumble, being disobedient to the word, to which they also were appointed. But you are a chosen generation, a royal priesthood, a holy nation, His own special people, that you may proclaim the praises of Him who called you out of darkness into His marvelous light; who once were not a people but are now the people of God, who had not obtained mercy but now have obtained mercy.
