This is a psalm sung by the pilgrims on their journey up to Jeru­salem. As they did so it didn’t es­cape their attention that the city was surrounded by mountains. Jerusalem was strategically situated. Derek Kidner paints the picture for us, ‘The hills and the holy city, much in view and much in mind to the pilgrims, make their presence felt again; and once more the thoughts they arouse are searching and fundamental, piercing to the realities behind these impressive sights’. This article is an exposition of Psalm 125.
