Hebrews 4:3-7

For only we who believe can enter his rest. As for the others, God said, “In my anger I took an oath: ‘They will never enter my place of rest,’” even though this rest has been ready since he made the world. We know it is ready because of the place in the Scriptures where it mentions the seventh day: “On the seventh day God rested from all his work.” But in the other passage God said, “They will never enter my place of rest.” So God’s rest is there for people to enter, but those who first heard this good news failed to enter because they disobeyed God. So God set another time for entering his rest, and that time is today. God announced this through David much later in the words already quoted
