isaiah 64:5 Thou meetest him that rejoiceth and worketh righteousness, those that remember thee in thy ways: behold, thou art wroth; for we have sinned: in those is continuance, and we shall be saved. - Free Bible Online

      5. meetest--that is, Thou makest peace, or enterest into covenant with him (see on Isa 47:3).
      rejoiceth and worketh--that is, who with joyful willingness worketh [GESENIUS] (Ac 10:35; Joh 7:17).
      those--Thou meetest "those," in apposition to "him" who represents a class whose characteristics "those that," &c., more fully describes.
      remember thee in thy ways-- (Isa 26:8).
      sinned--literally, "tripped," carrying on the figure in "ways."
      in those is continuance--a plea to deprecate the continuance of God's wrath; it is not in Thy wrath that there is continuance (Isa 54:7, 8; Ps 30:5; 103:9), but in Thy ways ("those"), namely, of covenant mercy to Thy people (Mic 7:18-20; Mal 3:6); on the strength of the everlasting continuance of His covenant they infer by faith, "we shall be saved." God "remembered" for them His covenant (Ps 106:45), though they often "remembered not" Him (Ps 78:42). CASTELLIO translates, "we have sinned for long in them ('thy ways'), and could we then be saved?" But they hardly would use such a plea when their very object was to be saved.
