Charles Ellicott Commentary Malachi 2:3

"Behold, I will rebuke your seed, and will spread dung upon your faces, even the dung of your feasts; and ye shall be taken away with it." — Malachi 2:3 (ASV)

I will corrupt your seed. — Better, I will destroy for you the seed — namely, of the crops. It must be remembered that because the people neglected to pay the tithes, the Levites were obliged to go and till the fields (Nehemiah 13:10). The Septuagint for “seed” reads “corn.”

Dung of your solemn feasts. — Or rather, of your festival sacrifices. (Psalms 118:27.) The dung of the sacrificial animals was to be carried to an unclean place outside the camp, and burnt there. The priests, because they had profaned God’s Name by offering unfit animals in sacrifice, were to be treated in the most ignominious manner.

And one shall take you away with it — that is, according to a Hebrew idiom, and you shall be carried away to it — you shall be treated like it.
