It was there all the time.

 

“If you turn away your foot from the Sabbath, from doing your pleasure on my holy day, and call the Sabbath a delight, the holy day of the Lord honorable, and shall honor Him, not doing your own ways, nor finding your own pleasure, nor speaking your own words, then you shall delight yourself in the Lord.”

- Isaiah 58:13-14 NKJV
