יֶשׁ־לְאֵ֣ל יָדִ֔י לַעֲשׂ֥וֹת עִמָּכֶ֖ם רָ֑ע וֵֽאלֹהֵ֨י אֲבִיכֶ֜ם אֶ֣מֶשׁ ׀ אָמַ֧ר אֵלַ֣י לֵאמֹ֗ר הִשָּׁ֧מֶר לְךָ֛ מִדַּבֵּ֥ר עִֽם־יַעֲקֹ֖ב מִטּ֥וֹב עַד־רָֽע׃
I have it in my power to do you harm; but the God of your father’s [house] said to me last night, ‘Beware of attempting anything with Jacob, good or bad.’
Genesis 31:29 (The Contemporary Torah, JPS 2006)
If Genesis is understood like a series of parables, perhaps Genesis 31:29 is teaching us about the nature of the Adversary.
