Psalms 71:15

15. Thy righteousness and thy salvation Two words literally translated and everywhere well defined. “God’s salvation stands to his righteousness in the relation of effect to cause. God has pledged himself to save those who put their trust in him, and as a righteous God he cannot deny himself.” Perowne. Compare Hebrews 6:10. See note on Psalms 71:19.

I know not the numbers That is, the limits, or measures, (Furst,) of the righteousness and salvation just spoken of. But the Hebrew word, which occurs nowhere else, may be taken in the sense of enumerations, as in English version, and applied to God’s acts of righteousness and salvation; and in this sense corresponds with the declarations of Psalms 40:5; Psalms 139:17-18. In either sense, however, the doctrine is the same. These numberless and limitless mercies call for endless praises.
