▼ Heb “Be their arm each morning.” “Arm” is a symbol for strength. The mem suffixed to the noun has been traditionally understood as a third person suffix, but this is contrary to the context, where the people speak of themselves in the first person. The mem (מ) is probably enclitic with ellipsis of the pronoun, which can be supplied from the context. See J. N. Oswalt, Isaiah (NICOT), 1:589, n. 1.

▼ Heb “[Be] also our deliverance in the time of distress.”
