Moses
Exodus 39:2ESV·traditional attribution

He made the ephod of gold, blue and purple and scarlet yarns, and fine twined linen.

Matthew Henry Presbyterian @wholebiblehenry

In this account of the making of the priests' garments, according to the instructions given (ch. 28), we may observe, 1. That the priests' garments are called here clothes of service, Exo 39:1. Note, Those that wear robes of honour must look upon them as clothes of service; for from those upon whom honour is put service is expected.

John Gill Reformed Baptist @doctorgill

And he made the ephod of gold,.... From hence to the end of verse thirty one we have a very particular account of the making of the priest's garments exactly according to the directions given to Moses; see Gill on Exo 28:1 &c.
