21 This is the sum of the tabernacle, even of the tabernacle of testimony, as it was counted, according to the commandment of Moses, for the service of the Levites, by the hand of Ithamar, son to Aaron the priest.

22 And Bezaleel the son of Uri, the son of Hur, of the tribe of Judah, made all that the Lord commanded Moses.

23 And with him was Aholiab, son of Ahisamach, of the tribe of Dan, an engraver, and a cunning workman, and an embroiderer in blue, and in purple, and in scarlet, and fine linen.

This chapter ends by giving a summary of the creation of the tabernacle. We hear, once again, that Bezaleel was the chief architect, and alongside him was Aholiab. It sounds like Aholiab specialized in the engravings and the embroidering, and that Bezaleel led in everything else.

We also hear that Ithamar, one of the sons of Aaron, is the scribe that has been recounting all of the work of the tabernacle to us. Aaron had four sons, and Ithamar was the youngest of them all. This is the first time we have heard of his work, in which he was chosen to witness and prove to the world the obedience of the Israelites in following the mandate of the Lord. We will hear of him a few more times in the other books of Moses.
