Shabbos x 70

• The number of times the word shabbos occurs in the Chumash is 70. 
• The number of times the word shabbos occurs with respect to shemitta is 17: 
• 10 in the BeHar segment, and 
• 7 in the BeChuqotei segment (with the interlude properly going to the BeHar segment, as the original segmentation of the chapters has it). 
• All 7 of the BeChuqotei occurences refer to the tokhachah. 
• The remaining occurences therefore number 53, of which 
• 3 are a repetition in Deuteronomy of the Decalogue's statement in Exodus, and 
• 1 is the story of the meqoshesh eitzim, which is narrative and not legislative. 
• That leaves variously 49 (7 x 7) or 50 instances. 
• The term shabbaton occurs 11 times: 
• 7 times as shabbat shabbaton, and 
• 4 times as shabbaton by itself: 
• one each for 
1. Yom haZikaron, 
2. Chag haAssif, 
3. Shemini Atzeret, and once for the 
4. sephiach qetzirkha for the land.
