And severally (to de kath' heis). A difficult late idiom where the preposition kath' (kata) is treated adverbially with no effect on the nominative case heis like huper egō (2Co 11:23). So heis kath' heis (Mar 14:19) and in Modern Greek katheis as a distributive pronoun. But we have kath' hena in 1Co 14:31. The use of the neuter article here to with kath' heis is probably the accusative of general reference, “as to each one.”
