Numbers 15:37 - 15:41
37 Yahweh also spoke to Moses, saying, 38 “Speak to the sons of Israel, and tell them that they shall make for themselves tassels on the corners of their garments throughout their generations, and that they shall put on the tassel of each corner a cord of blue. 39 And it shall be a tassel for you to look at and remember all the commandments of Yahweh, so as to do them and not follow after your own heart and your own eyes, after which you played the harlot, 40 so that you may remember to do all My commandments and be holy to your God. 41 I am Yahweh your God who brought you out from the land of Egypt to be your God; I am Yahweh your God.”
