Charles H. Spurgeon on Psalms 68:27

Their ruler. The prince of that tribe. The Greek version saith, in a trance; taking the Hebrew Mdr to be of Mdr, though it be not found elsewhere in this form; yet rare words but once used are sundry times found in this and other Psalms. These things applied to Christ's times and after are very mystical. Benjamin, the least, is put here first; so in the heavenly Jerusalem, the first foundation is a jasper (Re 21:19), which was the last precious stone in Aaron's breastplate, on which Benjamin's name was graven (Ex 28:10,20-21). In this tribe Paul excelled as a prince of God, though one of the least of the apostles (1Co 15:8-10), who was converted in a trance or ecstasy (Ac 9:3-4, etc.); and in ecstasies he and other apostles saw the mysteries of Christ's kingdom.
