Midrasch zu Schemot 16:12

Another comment on write thee (Exod. 34:27). Scripture states elsewhere: Let them be thine only, and not a stranger’s with thee (Prov. 5:17). What does this verse refer to? When they made the golden calf, Moses prayed until the Holy One, blessed be He, became reconciled with them. Moses cried out: My Master, restore the law to them just as David proclaimed: Restore unto me the joy of Thy salvation (Ps. 51:14). However, the Holy One, blessed be He, responded: How can I return it to them, when only yesterday they said at Sinai: All that the Lord hath spoken we will do (Exod. 24:17), and now, in the very place in which they committed themselves (to observe the law), they debased themselves, as it is said: They made a calf in Horeb (Ps. 106:19)? Despite all the miracles and wonders that I performed in their behalf in Egypt and at the Red Sea, and even though they beheld My Glory at Sinai, where myriads of angels descended and crowned them, as it is said: A beautiful crown upon thy head (Exod. 16:12), they erected a calf at Horeb. Indeed, within the blinking of an eye they forgot Me.
