Deuteronomy 6:25 - Wesley's Explanatory Notes

It shall be our righteousness — Heb. Righteousness shall be to us. We shall be owned and pronounced by God to be righteous and holy persons, if we sincerely obey him, otherwise we shall be declared to be unrighteous and ungodly. Or, mercy shall be to us, or with us. For as the Hebrew word rendered righteousness is very often put for mercy, (as Psalms 24:5, Psalms 36:10, Psalms 51:14; Proverbs 10:2, Proverbs 11:4; Daniel 9:16) so this sense seems best to agree both with the scripture use of this phrase, (in which righteousness, seldom or never, but grace or mercy frequently, is said to be to us or with us) and with the foregoing verse and argument God, saith he, Deuteronomy 5:24, commanded these things for our good, that he might preserve us alive, as it is this day. And, saith he in this verse, this is not all; for as he hath done us good, so he will go on to do us more and more good, and God's mercy shall be to us, or with us, in the remainder of our lives, and for ever, if we observe these commandments.
