Jeremiah 1:16

I will utter my judgments - God denounced his judgments: the conquest of their cities, and the destruction of the realm, were the facts to which these judgments referred; and these facts prove that the threatening was fulfilled.

Worshipped the works of their own hands - Idolatry was the source of all their wickedness and was the cause of their desolations. For למעשי lemaasey , the works, more than a hundred MSS. of Kennicott's and De Rossi's, with many editions, have למעשה lemaaseh , the work. Idolatry was their One great Work, the business of their life, their trade.
