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.
Rashi
ועשו להם ציצת THAT THEY MAKE THEM A FRINGE — It is called צצית, because of the threads that hang down from it. Similar is, (Ezekiel 8:3) “and he caught me by the curls (ציצת) of my head’’. (The word denotes something twisted as threads or curls). — Another explanation is: it is called ציצת because of the command associated with it (v. 39) “and ye shall look at it”. Similar is, “looking (מציץ) from the lattice” (Song 2:9). (The word therefore denotes “something looked at”) (Sifrei Bamidbar 115).
Rashbam
ציצית, similar to Ezekiel 8,3בציצת ראשי , a bunch of fringes suspended like the hair of one’s head.
Or HaChaim
Speak etc. and you shall say: Since there is an element of commandment as well as advantage, and honor which come from the commandment, therefore it said both Speaking (in a commanding form) and saying (in a gentle and respectful form).
