NET

21 But the children rebelled against me, did not follow my statutes, did not observe my regulations by carrying them out (the one who obeys them will live by them), and desecrated my Sabbaths. I decided to pour out my rage on them and fully vent my anger against them in the wilderness.

Darby

21 And the children rebelled against me: they walked not in my statutes, neither kept mine ordinances to do them, which if a man do, he shall live by them; they profaned my sabbaths: and I said I would pour out my fury upon them, to accomplish mine anger against them in the wilderness.

KJV

21 Notwithstanding the children rebelled against me: they walked not in my statutes, neither kept my judgments to do them, which [if] a man do, he shall even live in them; they polluted my sabbaths: then I said, I would pour out my fury upon them, to accomplish my anger against them in the wilderness.
