Parallel
Deuteronomy 33:5
Jewish Publication Society 1917 · Berean Standard Bible
And there was a king in Jeshurun, When the heads of the people were gathered, All the tribes of Israel together.
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.
