Instead of doing that, you found a quote you think proves there's nothing wrong with Alexandrian manuscripts.

You didn't address it either.

Exodus 13:2 was easiest passage to find, translate, and write down. If you want a passage from new testament or another translation let me know. This text in Codex Vaticanus doesn't match what is being said in "Against Heresies".

Against Heresies (Book I, Chapter 3)

4. They moreover affirm that the Saviour is shown to be derived from all the Æons, and to be in Himself everything by the following passage: "Every male that opens the womb." Exodus 13:2;

From Codex Vaticanus Exodus 13:2

1 Είπεν δε Κύριος προς Μωυσήν λέγων

2“Αγίασόν μοι πάν πρωτότοκον πρωτογενές δια- ! νοίγον πάσαν μήτραν εν τοις υιούς Ισραήλ από ανθρώπου έως κτήνους» εμοί εστιν.

3 Είπεν και δε Μωυσής προς τον λαόν Μνημονεύετε την ημέραν ταύτην εν ή εξήλθατε εκ γης Αιγύπτου, εξ οίκου δουλίας: έν γάρ χειρί κραταιά εξήγαγεν υμάς Κύριος εντεύθεν και ου βρωθήσεται ζύμη.

4έν γάρ τη σήμερον ύμείς εκπορεύεσθε εν μηνί των νέων.

5 και έσται ήνίκα εαν εισαγάγη σε 4 Κύριος ο Θεός σου εις την γήν των Χαναναίων και Χετταίων και Εύαίων και Γεργεσαίων και 'Αμορραίων και Φερεζαίων και Ιεβουσαίων, ήν ώμοσεν τους πατράσιν σου δούναι σοι, γήν ρέουσαν γάλα και μέλι, και ποιήσεις την λατρίαν ταύτην έν τω μηνί τούτω.

6εξ ημέρας έδεσθε και άζυμα, τη δε ημέρα τη εβδόμη εορτή Κυρίου: 7άζυμα έδεσθε επτά ημέρας, ουκ οφθήσεταί σοι

7 ζυμωτόν ουδέ έσται σοι ζύμη εν πάσιν τοϊς ορίοις σου.

8 και αναγγελείς τώ υιώ σου εν τη ημέρα και εκείνη λέγων Διά τούτο εποίησεν Κύριος ο Θεός μοι, ώς εξεπορευόμην έξ Αιγύπτου.

9 και έσται και σοι σημείον επί της χειρός σου και μνημόσυνον προ οφθαλμών σου, όπως αν γένηται ο νόμος Κυρίου εν τω στόματί σου· έν γαρ χειρί κραταια εξήγαγές σε Κύριος ο Θεός εξ Αιγύπτου.

1 And the LORD said unto Moses, saying.

2 Sanctify unto me all the firstborn of the firstborn, which hath opened every womb in the children of Israel, from man to beast.

3 And Moses also said unto the people, Remember this day, in which ye came out of the land of Egypt, out of the house of bondage: for the LORD hath brought you forth out of the land of Egypt with a mighty hand, and ye shall not find yeast.

4 For to day ye go forth in the month of youth.

5 And it shall be a good thing if the LORD thy God bring thee 4 Into the land of the Canaanites, and Hittites, and Hivites, and Hivites, and Gergesians, and Amorites, and Perizzites, and Jebusites, which he commanded thy fathers to give thee, a land flowing with milk and honey, and thou shalt feed thee in this month.

6Thou shalt be unleavened and unleavened bread six days, and the seventh day shall be the seventh feast of the LORD: 7Thou shalt be unleavened seven days, and they shall not do unto thee.

7 Ye shall have no leaven, neither shall ye have yeast in all thy days.

8 And thou shalt tell thy son in that day, and she shall say, This is what the LORD God hath done for me, when I came out of Egypt.

9 And there shall be a sign upon thy hand, and a memorial in thine eyes, as if the law of the LORD were done in thy mouth: for the LORD God hath brought thee out of Egypt with a mighty hand.
