Exodus 25:4

ותכלת AND BLUE PURPLE — wool dyed with the blood of the חלזון (a kind of shell-fish), the colour of which was greenish-blue (Menachot 44a). וארגמן AND RED PURPLE — wool coloured with a kind of dye the name of which is ארגמן ושש — this is what we call LINEN (Yevamot 4b). ועזים is GOATS’ HAIR; therefore Onkelos translates it by וּמְעַזֵּי which denotes something that comes from the goats — not the goats themselves, for the Aramaic translation of עזים is עִזַּיָּא‎.

and blue, and purple, and scarlet, and fine linen, and goats’ hair,

וּתְכֵ֧לֶת וְאַרְגָּמָ֛ן וְתוֹלַ֥עַת שָׁנִ֖י וְשֵׁ֥שׁ וְעִזִּֽים׃
