malachi 1:13 Ye said also, Behold, what a weariness is it! and ye have snuffed at it, saith the LORD of hosts; and ye brought that which was torn, and the lame, and the sick; thus ye brought an offering: should I accept this of your hand? saith the LORD. - Free Bible Online

      13. what a weariness is it!--Ye regard God's service as irksome, and therefore try to get it over by presenting the most worthless offerings. Compare Mic 6:3, where God challenges His people to show wherein is the "weariness" or hardship of His service. Also Isa 43:22-24, wherein He shows that it is they who have "wearied" Him, not He who has wearied them.
      snuffed at--despised.
      it--the table of the Lord, and the meat on it (Mal 1:12).
      torn--namely, by beasts, which it was not lawful to eat, much less to offer (Ex 22:31).
      thus . . . offering--Hebrew, mincha; the unbloody offering of flour, &c. Though this may have been of ordinary ingredients, yet the sacrifices of blemished animals accompanying it rendered it unacceptable.
