And in all things that I have said unto you, be circumspect,.... Or observe them, be careful to keep them punctually and constantly, even all that are delivered in this and the preceding chapters: and make no mention of the name of other gods; neither call upon them, nor swear by them, nor make vows to them; and, as little as possible, ever utter their names, and never with pleasure and delight, and showing any honour of them, and reverence to them, but with the utmost detestation and abhorrence: neither let it be heard out of thy mouth; not any of their names; the same thing in different words, the more to inculcate and impress the thing upon the mind, and to show with what vehemence and earnestness this is pressed.
