Charles Ellicott Commentary Psalms 68:27

"There is little Benjamin their ruler, The princes of Judah [and] their council, The princes of Zebulun, the princes of Naphtali." — Psalms 68:27 (ASV)

There is ... —The procession is apparently a representative one, and the conjecture is probable which attributes the selection of Zebulun and Naphtali to their prominence in Deborah’s song. Benjamin may owe its position to the fact that it gave the nation its first king, and Judah would naturally be prominent in the pomp as the tribe of David.

However, other considerations may also have had weight. The selection may have been made as representative of the two kingdoms.

Their ruler. —The Hebrew word, with the possible exception of Jeremiah 5:31, always conveys a sense of a high-handed conqueror’s rule. There is probably still a reference to Saul and his conquests—“little Benjamin who conquered for you,” or, possibly, here Benjamin takes the victor’s place as leader of the procession.

Their council. —The reading must certainly be changed in accordance with Psalms 55:14. It should be: Their crowd, or company.
