Verses with the word headlong in the Apocrypha (2 verses):
Wisdom of Solomon 4:19
For he shall rend them, and cast them down headlong, that they shall be speechless; and he shall shake them from the foundation; and they shall be utterly laid waste, and be in sorrow; and their memorial shall perish.
2 Maccabees 6:10
For there were two women brought, who had circumcised their children; whom when they had openly led round about the city, the babes handing at their breasts, they cast them down headlong from the wall.
