Tanach sobre Deuteronômio 22:12

And Adonoy spoke to Moshe, saying:

Speak to Bnei Yisroel and tell them to make for themselves, tzizis-fringes on the corners of their garments—throughout their generations; and they will place with the fringes of each corner a thread of blue.

And it will be to you for fringes and you will look upon it and you will remember all of Adonoy’s commandments and you will perform them; and you will not search after [the desire of] your hearts and after your eyes which cause you to go astray.
