Parallel
Deuteronomy 33:5
Brenton's English Septuagint · Berean Standard Bible
And he shall be prince with the beloved one, when the princes of the people are gathered together with the tribes of Israel.
So the LORD became King in Jeshurun (note: Jeshurun means the upright one, a term of endearment for Israel; also in verse 26.) when the leaders of the people gathered, when the tribes of Israel came together.
