Numbers 15:37-41

37Again the Lord spoke to Moses, saying,

38“Speak to the children of Israel: Tell them to make tassels on the corners of their garments throughout their generations, and to put a blue thread in the tassels of the corners.

39And you shall have the tassel, that you may look upon it and remember all the commandments of the Lord and do them, and that you may not follow the harlotry to which your own heart and your own eyes are inclined,

40and that you may remember and do all My commandments, and be holy for your God.

41I am the Lord your God, who brought you out of the land of Egypt, to be your God: I am the Lord your God.”
