For this God (i.e. the God who has now delivered us) is our God for ever and ever; i.e. he will always remain faithful to us, as we will to him. He will be our Guide even unto death. Dr. Kay translates "even over death," and understands that God's loving protection is promised to the faithful even in the land beyond the grave. But he stands alone in this interpretation. Host moderns question whether the words על־מוּת are any part of the psalm, and, comparing them with the על־מוּת לבּן of the title to Psalms 9:1-20; suggest that they are a mere musical notation. But the psalm would end abruptly without the words, and the meaning, "he will be our Guide unto death," is quite satisfactory (so Hengstenberg and the Revised Version).
