The Mark on Tobias Lear’s Lintel - A Passover Reference

The mark on Tobias Lear’s lintel means the Obturavi have found the Commander of the Clypeate, and they marked his house in preparation for a nighttime ambush.

The lintel mark is a biblical reference to Passover, in Exodus, when painting the door frame with lamb’s blood meant God would pass over the home and spare it. 

The lintel was the cross-beam or header of the door. 

Tobias Lear’s untimely death has been prophesied by Hesperus, and when he leaves the Epistolith’s Sanctuary and returns to his home, has become the Clypeate’s sacrificial lamb.
