Were our examples (tupoi hēmōn egenēthēsan). More exactly, examples for us (objective genitive hēmōn, not subjective genitive, of us). The word tupoi (our types) comes from tuptō, to strike, and meant originally the mark of a blow as the print of the nails (Joh 20:25), then a figure formed by a blow like images of the gods (Act 7:43), then an example to be imitated (1Pe 5:3; 1Ti 4:12; 1Th 1:7; 2Th 3:9), or to be avoided as here, and finally a type in a doctrinal sense (Rom 5:14; Heb 9:24).
To the intent we should not lust after (eis to mē einai hēmas epithumētas). Purpose expressed by eis with the articular infinitive to einai and the accusative of general reference with epithumētas (lusters) in the predicate.
