O continue thy lovingkindness to them that know thee,.... That is, spiritually and experimentally; and such are they that trust in him and love him: and these are the objects of the love of God; not that their knowledge, faith, or love, are the cause of his love to them; but these things describe and point at manifestly the objects of it; and this request regards the open discovery of it unto them: for the love of God itself always continues, though the manifestations of it are not always the same; and it is for the enlargement and continuance of them the psalmist here prays: for it may be rendered, "draw out thy lovingkindness" (g); that is, to a greater length; make a larger and clearer discovery of it, that the height and depth, and length and breadth of it, may be more discerned; and thy righteousness unto the upright in heart; who are sincere and without guile; who have new hearts created and right spirits renewed in them, and have truth in the inward parts; and unto and upon such is the righteousness of Christ, and where it always continues, for it is an everlasting one; but here it means a clearer and constant revelation of it from faith to faith; unless it should rather intend the righteousness of God in protecting his people from the insults of their enemies, and the continual exertion of it for that purpose.
