The LORD is their strength, and he is the saving strength of his anointed.
Their strength. "The Lord," whom he had called "my strength" (Psalms 28:7), he now calls "their strength;" so wholly identified is his cause with that of his people.
He is the saving strength - literally, the strength of saving deliverances. In saving his anointed king, God saves the people over whom He has anointed him (Psalms 18:50; cf. Psalms 28:9).
