In Ki Tisa, Moses, begs God to let him understand the Divine. And yet, we see Moses as having more access to God than any other man. If Moses cannot comprehend God, how can we hope to understand God’s ways?
In Ki Tisa, when God says to Moses, Hinei makom Iti, "Here is a place with me," God may have been pointing Moses to the perfect spot in the cleft in the rock. For the rest of us, spread across the earth, who might wish for a place by God, Ki Tisa directs us, as well. For us, Shabbat can be this place.
