Exodus 31:16

and the sons of Israel have observed the sabbath; to keep the sabbath to their generations is a covenant age-during,

My bow I have given in the cloud, and it hath been for a token of a covenant between Me and the earth;

and ye have circumcised the flesh of your foreskin, and it hath become a token of a covenant between Me and you.

To Zion they ask the way, Thitherward are their faces: Come in, and we are joined unto Jehovah, A covenant age-during -- not forgotten.

Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant.

My bow I have given in the cloud, and it hath been for a token of a covenant between Me and the earth;

and ye have circumcised the flesh of your foreskin, and it hath become a token of a covenant between Me and you.

To Zion they ask the way, Thitherward are their faces: Come in, and we are joined unto Jehovah, A covenant age-during -- not forgotten.

And My sabbaths sanctify, And they have been for a sign between Me and you, To know that I, Jehovah, am your God.
