Matthew Poole and continuators on Numbers 15:39

39 And it shall be unto you for a fringe , that ye may look upon it, and remember all the commandments of the LORD, and do them: and that ye seek not after your own heart, and your own eyes , after which ye use to go a whoring :

It (i. e.) the ribband, shall be unto you, i. e. shall serve you for the fringe, to wit, to render it more visible and notorious by its certain and remarkable and distinct colour, whereas the fringe without this was of the same piece and colour with the garment and therefore less observable. Or, it, (i. e.) the ribband, shall be in your fringes, or, put to your fringes, fastened to them.

That by looking upon it you may remember, that your eye may affect your mind and heart.

Or, inquire not for other rules or ways of serving me than I have prescribed you.

(i. e.) Neither after the devices and inventions of your own minds or hearts, as Nadab and Abihu did when they offered strange fire, and as you now did when you pretended to serve and please me by going up the hill and towards Canaan without and against my command; nor after the examples or inventions of others which your eyes see, as you did when you were set upon worshipping a calf after the manner of Egypt.

(i. e.) To depart from me, and to prefer your o[illegible: 1+ letters]n fancies before my commands, and to live onely by present sight or sence, and not at all by faith in my promises.
