Jesus spoke Aramaic. Not Greek. Greek has masculine and feminine nouns. In Aramaic, there would be no confusion of gender.
“Jesus spoke Aramaic. Not Greek.”
“After Alexander, Palestine was ruled by the Ptolemies and the Seleucids for almost two hundred years. Jewish culture was heavily influenced by Hellenistic culture, and Koine Greek was used not only for international communication, but also as the first language of many Jews.”

However, I think we can safely assume that the Son of God could speak whatever language He wished to speak, just as He knew Scripture backwards and forwards without any formal training, and knew the nature of life and mankind better than any trained philosopher of His day.
Prove it.

The NT was God breathed, Holy Spirit inspired in Greek so whether Jesus spoke Aramaic or not is irrelevant.
You can't base an argument on what someone might have said if they had been speaking another language as it is pure speculation.
