Exodus 16:21-30
21 Morning by morning they gathered it, each as much as he could eat; but when the sun grew hot, it melted.
22 On the sixth day they gathered twice as much bread, two omers each. And when all the leaders of the congregation came and told Moses, 23 he said to them, “This is what the Lordhas commanded: ‘Tomorrow is a day of solemn rest, a holy Sabbath to the Lord; bake what you will bake and boil what you will boil, and all that is left over lay aside to be kept till the morning.’”24 So they laid it aside till the morning, as Moses commanded them, and it did not stink, and there were no worms in it. 25 Moses said, “Eat it today, for today is a Sabbath to the Lord; today you will not find it in the field. 26 Six days you shall gather it, but on the seventh day, which is a Sabbath, there will be none.”
27 On the seventh day some of the people went out to gather, but they found none. 28 And the Lord said to Moses, “How long will you refuse to keep my commandments and my laws? 29 See! The Lord has given you the Sabbath; therefore on the sixth day he gives you bread for two days. Remain each of you in his place; let no one go out of his place on the seventh day.” 30 So the people rested on the seventh day.
Hebrews 4:9-13
9 So then, there remains a Sabbath rest for the people of God, 10 for whoever has entered God's rest has also rested from his works as God did from his.
11 Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience. 12 For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. 13 And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account.
