Ezekiel 20:21

20:21 “‘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.

Exodus 16:27-28

16:27 On the seventh day some of the people went out to gather it, but they found nothing. 16:28 So the Lord said to Moses, “How long do you refuse to obey my commandments and my instructions?

Numbers 15:31-36

15:31 Because he has despised the word of the Lord and has broken his commandment, that person must be completely cut off. His iniquity will be on him.’”

15:32 When the Israelites were in the wilderness they found a man gathering wood on the Sabbath day. 15:33 Those who found him gathering wood brought him to Moses and Aaron and to the whole community. 15:34 They put him in custody, because there was no clear instruction about what should be done to him. 15:35 Then the Lord said to Moses, “The man must surely be put to death; the whole community must stone him with stones outside the camp.” 15:36 So the whole community took him outside the camp and stoned him to death, just as the Lord commanded Moses.

Isaiah 56:6

56:6 As for foreigners who become followers of the Lord and serve him,

who love the name of the Lord and want to be his servants –

all who observe the Sabbath and do not defile it,

and who are faithful to my covenant –
