This Website http://lionlamb.net/v3/YAVOH-HeisComing/2004/07 provides numerous examples where the standard Hebrew text of the Old Testament has some larger and smaller than regular letters (e.g., Genesis 1:1; Deuteronomy 6:4) as well as dots over some letters (Deuteronomy 29:29). Some of these are noted in the Logos versions of BHS (like the dots in Deuteronomy 29:29) but the changed letter sizes are not.
WHEN did these orthographic things appear in the Hebrew text? Is there any evidence that they are in the Dead Sea Scrolls texts of these passages? Or were they done by the Masoretes? Any idea how far back the traditions about these particular things go - i.e., were they known to Jesus and Paul; did their Torahs have these orthographic characteristics?
(Some refer to these as "jots and tittles" apparently.)
