Charles Ellicott Commentary Jeremiah 17:15

"Behold, they say unto me, Where is the word of Jehovah? let it come now." — Jeremiah 17:15 (ASV)

Behold, they say to me. —The speakers are not named or defined, but they are clearly the mockers who questioned Jeremiah’s prophetic character, on the ground that his threats had received no fulfillment. Presumably, therefore, the words were written before the death of Jehoiakim and the capture of Jerusalem.

Let it come now. —The last word is the usual formula of request, and implies a mocking tone in the speakers: “Let it come, if you please.”
