Numbers 15:40

That ye may remember and do all my commandments,.... Which is repeated, that the end and use of these fringes might be particularly taken notice of, and attended to; that so they might not satisfy themselves with and rest in this ceremony of wearing the fringes, but be found in the observance of every moral precept, and of every religious ordinance and duty:

and be holy unto your God: as in his presence, according to his will, and for his honour and glory, by keeping his holy commands, and living an holy life and conversation, well pleasing in his sight.
