Exodus 38:8

38:8 He made the large basin of bronze and its pedestal of bronze from the mirrors of the women who served ¹  at the entrance of the tent of meeting.

Exodus 39:41

39:41 the woven garments for serving ²  in the sanctuary, the holy garments for Aaron the priest, and the garments for his sons to minister as priests.

¹ sn The word for “serve” is not the ordinary one. It means “to serve in a host,” especially in a war. It appears that women were organized into bands and served at the tent of meeting. S. R. Driver thinks that this meant “no doubt” washing, cleaning, or repairing (Exodus, 391). But there is no hint of that (see 1 Sam 2:22; and see Ps 68:11 [12 Hebrew text]). They seem to have had more to do than what Driver said.

² tn The form is the infinitive construct; it means the clothes to be used “to minister” in the holy place.
