Psalms 68:15 - Joseph Benson’s Commentary on the Old and New Testaments

The hill of God That is, Zion, the seat of God's ark; is as the hill of Bashan Equal, yea, superior to it. Bashan was a rich and fruitful mountain beyond Jordan, called by the LXX. πιον ορος, a fat mountain, and ορος τετυρωμενον, a mountain that yielded much butter and cheese. But Zion had greater advantages, and yielded much better fruits. A high hill as the hill of Bashan Though it be but a low, mean hill, compared with Bashan, in outward appearance, yet it is as high as it, yea, is exalted far above it, through its spiritual privileges, being the place where God's worship is established, where he is peculiarly present, and where he confers his choicest blessings; in which respect the mountain of the Lord's house is said to be established on the top of the mountains, and exalted above the hills. Dr. Chandler supposes that this and the two following verses were begun to be sung when the ark came in view of mount Zion, the place of its fixed residence for the future, and probably when they began to ascend the hill. And he reads this, as well as the following verse, with an interrogation, conceiving that it makes them appear more suitable to the occasion, and worthy of the genuine spirit of poetry; thus: Is the hill of Bashan, is the craggy hill of Bashan the hill of God? As if he had said, Bashan may boast of its proud eminences, its craggy summits, but is this the hill where God will fix his residence?
