Here is another request from the McMaster Museum of Art.
I suspect the correct Latin for this is
Abraham ad filii mactationem sese apparans prohibetur ab angelo
which would be translated
Abraham, preparing for the slaughter of his son, is prevented by an angel
This depicts the moment described in Genesis 22:10-12. Notice the ram in the background, anticipating Genesis 22:13. That’s a nice touch. I like Abraham’s sword.
