Jamieson, Fausset and Brown on Exodus 35:30

30. See, the Lord hath called by name Bezaleel, the son of Uri, &c.--Moses had made this communication before [see Ex 31:2-5; also see on Ex 31:2]. But now that the collection had been made, the materials were contributed, and the operations of building about to be commenced, it was with the greatest propriety he reminded the people that the individuals entrusted with the application of their gold and silver had been nominated to the work by authority to which all would bow.
