דַּבֵּ֞ר אֶל־בְּנֵ֤י יִשְׂרָאֵל֙ וְאָמַרְתָּ֣ אֲלֵהֶ֔ם וְעָשׂ֨וּ לָהֶ֥ם צִיצִ֛ת עַל־כַּנְפֵ֥י בִגְדֵיהֶ֖ם לְדֹרֹתָ֑ם וְנָֽתְנ֛וּ עַל־צִיצִ֥ת הַכָּנָ֖ף פְּתִ֥יל תְּכֵֽלֶת׃
רעד צו די קינדער פֿון ישׂראל, און זאָלסט זאָגן צו זײ, זײ זאָלן זיך מאַכן פֿרענדז אױף די עקן פֿון זײערע קלײדער, אױף זײערע דָור-דורות; און זײ זאָלן אַרײַנטאָן אין די פֿרענדז פֿון עק קלײד אַ בלאָען פֿאָדים.
Siddur Edot HaMizrach
And the L·rd spoke unto Moses, saying, speak unto the children of Israel & say to them to make for themselves a fringe on the borders of their garments, throughout their generations. And they shall place upon the fringe of the border, a thread of blue wool.(From the sea worm bonellia viridis) And it shall be to you a fringe that you may look upon, & remember all the commandments of the L·rd & to do them. Then shall you not stray after your heart & your eyes whereafter you are wont to stray. So may you remember & do all My commandments & be holy for your G·d. I am the L·rd your G·d who brought you out of the land of Egypt to be your G·d; I am the L·rd your G·d. (Bamidbar / Numbers 15:37-41) True.
