I’m guessing this is a representation of the biblical account of Jael and Sisera.

Honestly, it’s an uncharacteristically feminist story of a woman (Deborah) prophet and Judge (older person viewed as a respected authority), who summons a man (Barak) and tells him he will go and war against the occupiers/oppressors of the land. When Barak asks for Deborah to go with him, she tells him the victory will go to a woman. Once the enemy is routed, the chief of the occupying army (Sisera) flees to the home of a neutral party (Heber), who happens to not be in the home. Heber’s wife (Jael) recognizes the general, claims to give him sanctuary, drugs him, and kills him by driving a tent pin through his skull via the temple.

NGL, kinda metal
