Exodus 26:1

ואת המשכן תעשה עשר יריעת MOREOVER THOU SHALT MAKE THE DWELLING OF TEN CURTAINS — that they should serve it as a roof and at the same time as wall-coverings for the outside of the boards; — for the curtains hung behind them so as to cover them. שש משזר ותכלת וארגמן ותלעת שני OF FINE TWINED LINEN AND BLUE PURPLE, AND RED PURPLE, AND CRIMSON — Thus there were four different materials in every thread, one of linen and three of wool, each of the strands of which a thread was composed being sixfold (the word is taken here in the double sense of שש “linen” and of שש “six”). Consequently the four materials intertwined into one thread gave a twenty-four-fold thread (Yoma 71b; Baraita DeMelekhet HaMishkan ch. 2). כרבים מעשה חשב WITH CHERUBIM, THE WORK OF AN ARTIST — Cherubim were figured on them (on the curtains) in the process of weaving them, not afterwards by embroidery which is needlework — but by weaving it on its two surfaces, one design on one side, a different design on the other; e. g., a lion on one side and an eagle on the other side, just as the silken girdles are woven which are called in old French faisee (Yoma 72b, Jerusalem Talmud Shekalim 8:4).

וְאֶת־הַמִּשְׁכָּ֥ן תַּעֲשֶׂ֖ה עֶ֣שֶׂר יְרִיעֹ֑ת שֵׁ֣שׁ מׇשְׁזָ֗ר וּתְכֵ֤לֶת וְאַרְגָּמָן֙ וְתֹלַ֣עַת שָׁנִ֔י כְּרֻבִ֛ים מַעֲשֵׂ֥ה חֹשֵׁ֖ב תַּעֲשֶׂ֥ה אֹתָֽם׃

Moreover thou shalt make the tabernacle with ten curtains of fine twined linen, and blue, and purple, and scarlet: with keruvim of artistic work shalt thou make them.
