Charles Ellicott Commentary Exodus 28:5

"And they shall take the gold, and the blue, and the purple, and the scarlet, and the fine linen." — Exodus 28:5 (ASV)

They shall take gold, and blue. —Hebrew, the gold and the blue, etc.—i.e., they (the wise-hearted men of Exodus 28:3) shall receive (from Moses) the (necessary) gold, blue, etc., for the construction of the vestments. It is to be noted that the materials are the same as those employed for the veil and curtains of the sanctuary (Exodus 26:1; Exodus 26:31; Exodus 26:36), but with the further addition of gold and precious stones (Exodus 28:9; Exodus 28:17–21).
