The 7th Day of Hanukkah...

And God rested on the 7th Day...

Genesis 2

Thus the heavens and the earth were finished, and all the host of them. 2 And on the seventh day God finished his work which he had done, and he rested on the seventh day from all his work which he had done. 3 So God blessed the seventh day and hallowed it, because on it God rested from all his work which he had done in creation.

4 These are the generations of the heavens and the earth when they were created. (RSVCE)

Keep Holy the Sabbath Day...

Exodus 20

8 “Remember the sabbath day, to keep it holy. 9 Six days you shall labor, and do all your work; 10 but the seventh day is a sabbath to the Lord your God; in it you shall not do any work, you, or your son, or your daughter, your manservant, or your maidservant, or your cattle, or the sojourner who is within your gates; 11 for in six days the Lord made heaven and earth, the sea, and all that is in them, and rested the seventh day; therefore the Lord blessed the sabbath day and hallowed it.
