Exodus 28:39

Embroider. The “coat” was a long, white linen gown or tunic worn over the “linen breeches” or drawers (see verse 42).

Of the girdle. This was made of “fine twined linen” of variegated colors and was artistically embroidered (Exodus 39:29).

Of needlework. Literally, “the work of an embroiderer.” Since the girdle was worn directly over the coat and under the robe of the ephod, it was not seen. Though hidden, it was costly and beautiful. Thus was taught the lesson that things devoted to God’s service, whether or not they are seen, should be of the best. Our motive in doing God’s work should be to honor God, not merely to do what will be pleasing in the sight of men (Galatians 1:10; 1 Thessalonians 2:4). True piety will make no difference between the seen and the unseen, between that which is hidden and that which is open to sight, but will strive, rather, after sincerity, honesty, and fitness in all that pertains to God (Ephesians 6:5-7).
