Exodus 39:3

39:3 They hammered the gold into thin sheets and cut it into narrow strips to weave them into the blue, purple, and scarlet yarn, and into the fine linen, the work of an artistic designer.

tn The verb is the infinitive that means “to do, to work.” It could be given a literal rendering: “to work [them into] the blue….” Weaving or embroidering is probably what is intended.
