וְלֹא תוֹנוּאִישׁ אֶת עֲמִיתוֹ וְיָרֵאתָ מֵאֱלֹקיךָ כִּי אֲנִי ה’ אֱלֹקיכֶם
Do not wrong one another; you shall fear your G-d because I am Hashem, your God.
The Hebrew word for G-d – “Elokim” – is plural in form. The two forms used in this verse – “Elokecha” and “Elokeichem” (“your G-d” and “the G-d of all of you,” respectively) reflect this plural form. While it should be obvious that the word is truly singular (after all, the verse does say “I am” and not “we are”), Onkelos takes an extra step to ensure that no mistakes are made. He renders these words “Elahach” and “Elahachon” – the Aramaic translation of the singular form – so that no readers might possibly be misled into thinking that there are multiple deities.
