The most recent Good Omens fics I've posted at the Ao3:
Two set in Iron Age Israel:
In Presence of My Foes - G
Crowley checks out a young singer from Bethlehem, and is glad to see he's no threat to his plans.
Depart From Me - G
Aziraphale and Crowley listen to music during an evening in King Saul's house in Gibeah, and find they're not the only creatures listening.
And one in a series focusing on Hastur and Ligur:
Five times Hastur and Ligur Weren't Betrayed, and One Time They Were - M
Hastur and Ligur succeed due to the hard work of others. Until someone tells a secret.
