See, I {a} have called by name Bezaleel the son of Uri, the son of Hur, of the tribe of Judah:

(a) I have chosen and made meet, Ex 35:30.

Wesley's Notes

31:2 See I have called Bezaleel, the grandson of Hur, probably that Hur who had helped to hold up Moses's hand, Ex 17:10 - 12, and was at this time in commission with Aaron for the government of the people in the absence of Moses. Aholiab of the tribe of Dan is appointed next to Bezaleel, and partner with him. Hiram, who was the head - workman in the building of Solomon's temple, was also of the tribe of Dan, 2Chron 2:14.

Jamieson-Fausset-Brown Bible Commentary

2. See, I have called-Though the instructions about the tabernacle were privately communicated to Moses, it was plainly impossible that he could superintend the work in person, amid the multiplicity of his other duties. A head director or builder was selected by God Himself; and the nomination by such high authority removed all ground of jealousy or discontent on the part of any who might have thought their merits overlooked (compare Mt 18:1).

by name Bezaleel-signifying "in the shadow or protection of God"; and, as called to discharge a duty of great magnitude-to execute a confidential trust in the ancient Church of God, he has his family and lineage recorded with marked distinction. He belonged to the tribe of Judah, which, doubtless for wise and weighty reasons, God all along delighted to honor; and he was the grandson of Hur, a pious patriot (Ex 17:12), who was associated, by a special commission, with Aaron in the government of the people during the absence of Moses. Moreover, it may be noticed that a Jewish tradition affirms Hur to be the husband of Miriam; and if this tradition may be relied on, it affords an additional reason for the appointment of Bezaleel emanating from the direct authority of God.

Matthew Henry's Concise Commentary

31:1-11 The Israelites, who had been masons and bricklayers in Egypt, were not qualified for curious workmanship; but the Spirit who gave the apostles utterance in divers tongues, miraculously gave Bezaleel and Aholiab the skill that was wanting. The honour which comes from God, is always attended with a work to be done; to be employed for God is high honour. Those whom God calls to any service, he will find or make fit for it. The Lord gives different gifts to different persons; let each mind his proper work, diligently remembering that whatever wisdom any one possesses, the Lord put it in the heart, to do his commandments.
