Psalms 78:51

⁵¹And he smote all the first engendered thing(s) in the land of Egypt or And he smote all the first begotten in the land of Egypt; the first fruits of all the travail of them in the tabernacles of Ham. (And he struck down all the first-born in the land of Egypt; yea, the first fruits of all their travail in the tents of Ham.)
