Охолиаб

Oholiab son of Ahisamach, from the tribe of Dan, was appointed by God alongside Bezalel as the chief artisan for the construction of the tabernacle and its furnishings (Exodus 31:6; 35:34–35; 38:23). While Bezalel of Judah handled the primary construction work, Oholiab specialized in engraving, design work, and embroidery in blue, purple, and scarlet yarn. Together they trained others in the sacred crafts and executed all the detailed specifications Moses had received from God on Sinai. The pairing of a Judahite and a Danite craftsman may reflect a deliberate inclusion of the two 'outer' tribes of the camp's arrangement.
