O Lord — The prophet contemplating the judgment which was now coming upon God's people, directs his prayer to God for them. Their arm — Our arm or strength. The change of persons is frequent in prophetical writings. Every morning — When we offer the morning sacrifice, and call upon thee: which yet is not meant exclusively, as if he did not desire God's help at other times; but comprehensively, the morning being put for the whole day. The sense is, help us speedily and continually.
