God is our refuge and strength - God is for us as a place to which we may flee for safety; a source of strength to us in danger. The first word, “refuge,” from a verb meaning to “flee,” and then “to flee to” - הסה châsâh - or to take shelter in - denotes a place to which one would flee in time of danger - as a lofty wall; a high tower; a fort; a fortress. See the notes at Psalms 18:2. The idea here is, that the people of God, in time of danger, may find him to be what such a place of refuge would be. Compare Proverbs 18:10. The word “strength” implies that God is the source of strength to those who are weak and defenseless; or that we may rely on his strength “as if” it were our own; or that we may feel as safe in his strength as though we had that strength ourselves. We may make it the basis of our confidence as really as though the strength resided in our own arm. See the notes at Psalms 18:2.
A very present help - The word “help” here means aid, assistance. The word “trouble” would cover all that can come upon us which would give us anxiety or sorrow. The word rendered “present” - נמצא nimetsâ' - means rather, “is found,” or “has been found;” that is, he has “proved” himself to be a help in trouble. The word “present,” as if he were near to us, or close by us, does not accurately express the idea, which is rather, that “he has been found” to be such, or that he has always “proved” himself to be such a help, and that, therefore, we may now confide in him. The word “very,” or “exceedingly,” is added to qualify the whole proposition, as if this were “emphatically true.” It was true in the most eminent sense that God had always been found to be such a helper, and, “therefore,” there was nothing to fear in the present distress. Psalms 46:2.
