Chasidut על שמות 35:2

Exodus 35,2. “but as far as the seventh day is concerned, it ‎shall be holy for you;” it ‎is to be understood as similar to what the sages said ‎‎(Pessachim 68) concerning the festival days, which they ‎view as ‎חציו לה' וחציו לכם‎, “half for G-d and half for you.” On the Sabbath, even the לכם (“for you”) is for G-d. “...it ‎shall be holy for you,” the for you is to be made holy.
