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.

Ye said also, Behold, 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 Micah 6:3, where God challenges his people to show wherein is the "weariness" or hardship of His service. Also Isaiah 43:22, wherein He shows that it is they who have "wearied" Him, not He who has wearied them.

And ye have snuffed at it - despised it.

It - the table of the Lord, and the meat on it (Malachi 1:12).

And ye brought that which was torn - namely, by beasts, which it was not lawful to eat, much less to offer (Exodus 22:31).

Thus ye brought an offering - Hebrew [ haminchaah (H4503)], minchah: the unbloody offering of flour, etc.

Should I accept this of your hand? saith the Lord. Though this may have been of ordinary ingredients, yet the sacrifices of blemished animals accompanying it rendered it unacceptable.
