The Lord is their strength,.... The strength of his people, mentioned in Psa 28:9; not only the strength of David in particular, but of all his people in general; see Psa 37:39; and he is the saving strength of his anointed; meaning either himself, as before, who was anointed by Samuel king of Israel, and therefore had not invaded and thrust himself into an office he had no call and right unto; or the Messiah, the Lord's Anointed, whom he heard, helped, and strengthened in the day of salvation, and delivered him from the power of death and the grave, and raised him from thence, and gave him glory; see Psa 20:6.
