For example:
1) The Bible says regarding Noe's raven that it didn't return to the Ark "έως ου εξηράνθη τα ύδατα" (= *eos ooh* the waters had been dried up). But since it didn't return to the Ark before the waters had dried up, when it had nowhere to stand upon, what happened then; it returned when the waters had dried up?!
2.) The Bible says: "Said the Lord to my Lord; sit on my right έως αν θω τους εχθρούς σου υποπόδιον των ποδών σου" *i.e.* “*eos an*” I place your enemies under your feet. I ask therefore: after the submission of His enemies, will Christ cease to sit on the right hand of the Father?!
3.) Elsewhere again the Lord tells His apostles: "with you I am all the days έως της συντελείας του αιώνος" *i.e.* "until the end of the eon". OK, I ask again: isn't Christ going to be with His disciples after the end of the eon in Heaven?
4.) The OT also says regarding the barren woman, Melchol: "και τη Μελχώλ ... ουκ εγένετο παιδίον έως της ημέρας του αποθανείν αυτήν" ( = "she had no child until the day she died"). According to the Protestant interpretation,* i.e.* interpreting the word "*eos*" not as "never", we must deduce that Melchol must have born a child after her death, when she was in her grave!
In fact, the term "έως ου" is used in the same way even today in Modern Greek. For example the teacher tells the children: "Keep quiet 'έως ότου' *eos otou*] I return"; until I return "*otou*" being the modern Greek equivalent of "*ou*" here]. Does he mean that, after his return, the children must be noisy? On the contrary! The teacher is only interested that they keep quiet till he comes back. Afterwards, it follows that they must be quiet when he is present!
So clearly the Evangelist is interested to prove that Panagia [the All-Holy Virgin] was a Virgin until (*eos*) Christ's birth, Who was born supernaturally, from the Spirit the Holy, and He is not son of Joseph's but Son of God. Regarding the issues after the birth, these are of no interest in the semantics of this sentence. It was obvious that she stayed a Virgin, since she had been honoured to bear the All-Holy Word in the first place.
