Exodus 28:31

28:31 “You are to make the robe ¹  of the ephod completely blue.

Exodus 39:22

The Other Garments

39:22 He made the robe of the ephod completely blue, the work of a weaver.

Exodus 29:5

29:5 and take the garments and clothe Aaron with the tunic, ²  the robe of the ephod, the ephod, and the breastpiece; you are to fasten the ephod on him by using the skillfully woven waistband. ³ 

[28:31]  ¹ tn The מְעִיל (mÿ’il), according to S. R. Driver (Exodus, 307), is a long robe worn over the ephod, perhaps open down the front, with sleeves. It is made of finer material than ordinary cloaks because it was to be worn by people in positions of rank.

[29:5]  ² tn The Hiphil of לָבַשׁ (lavash, “to clothe”) will take double accusatives; so the sign of the accusative is with Aaron, and then with the articles of clothing. The translation will have to treat Aaron as the direct object and the articles as indirect objects, because Aaron receives the prominence in the verse – you will clothe Aaron.

[29:5]  ³ tn The verb used in this last clause is a denominative verb from the word for ephod. And so “ephod the ephod on him” means “fasten as an ephod the ephod on him” (S. R. Driver, Exodus, 316).
