38"Speak to the people of Israel, and bid them to make tassels on the corners of their garments throughout their generations, and to put upon the tassel of each corner a cord of blue; 39and it shall be to you a tassel to look upon and remember all the commandments of the LORD, to do them, not to follow after your own heart and your own eyes, which you are inclined to go after wantonly.
