Charles Ellicott Commentary Exodus 38:23

"And with him was Oholiab, the son of Ahisamach, of the tribe of Dan, an engraver, and a skilful workman, and an embroiderer in blue, and in purple, and in scarlet, and in fine linen." — Exodus 38:23 (ASV)

Aholiab ... an engraver. —This is a mistranslation. Khârâsh means a worker in any material whatsoever. It should be rendered artificer, as it is in 1 Chronicles 29:5; 2 Chronicles 34:11.

A cunning workman. —Literally, a deviser; but the root is used especially of the devising of textile fabrics. (Exodus 26:31; Exodus 28:6; Exodus 28:15; Exodus 36:8; Exodus 36:35; Exodus 39:3, etc.)
