1. Paleo-Hebrew (Pre-Exilic Script)
o Used before the Babylonian exile (pre-586 BCE), this was the original alphabetic script of Israel, seen in inscriptions like the Siloam Inscription. Texts like the Torah (Genesis–Deuteronomy) were likely first written in this script.
o Content: Affirms YHWH as one. Deuteronomy 6:4 in Paleo-Hebrew would read roughly as יהוה אלהינו יהוה אחד (YHWH Eloheinu YHWH echad)—“YHWH our God, YHWH is one.” No hint of plurality.

2. Aramaic (Post-Exilic Influence)
o After the exile, Aramaic became the lingua franca of the Near East. Some early Scriptures or oral traditions (e.g., Targums) were influenced by Aramaic, though the canonical text stayed Hebrew. Fragments like the Dead Sea Scrolls (e.g., 1QGen) show Aramaic alongside Hebrew.
o Content: Still monotheistic. Isaiah 45:5—“I am YHWH, and there is no other”—would be consistent, even if transliterated into Aramaic script. No second or third deity emerges.

3. Square Script (Ketav Ashuri, No Vowels)
o Developed during/after the exile (5th–3rd century BCE), this became the standard Hebrew script, used in the Masoretic Text (e.g., Aleppo Codex, 10th century CE, based on earlier manuscripts). It’s vowelless—e.g., יהוה (YHWH) is written without pronunciation aids.
o Content: Identical to earlier texts. Exodus 20:2-3: אנכי יהוה אלהיך (Anokhi YHWH Eloheikha)—“I am YHWH your God… no other gods.” One God, no ambiguity.
