God's covenant with the earth
Genesis 9:12-15 (New International Version)

And God said, "This is the sign of the covenant I am making between me and you and every living creature with you, a covenant for all generations to come: I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth.

Whenever I bring clouds over the earth and the rainbow appears in the clouds, I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life."

The sabbath commandment and creation
Exodus 20:8-11 (JPS)

Remember the sabbath day and keep it holy. Six days you shall labor and do all your work, but the seventh day is a sabbath of the LORD your God: you shall not do any work — you, your son or daughter, your male or female slave, or your cattle, or the stranger who is within your settlements. For in six days the LORD made heaven and earth and sea, and all that is in them, and He rested on the seventh day; therefore the LORD blessed the sabbath day and hallowed it.

And rest for animals
Exodus 23:12 (JPS)

Six days you shall do your work, but on the seventh day you shall cease from labor, in order that your ox and your ass may rest, and that your bondman and the stranger may be refreshed.
