Charles Ellicott Commentary Jeremiah 10:15

"They are vanity, a work of delusion: in the time of their visitation they shall perish." — Jeremiah 10:15 (ASV)

The work of errors. —Better, a work of mockery, i.e., worthy of that and of that only, the word being apparently substituted, after Jeremiah’s manner, for the technical word, not unlike in sound, which is translated image work in 2 Chronicles 3:10.

In the time of their visitation. —i.e., in the time when they are visited with punishment, as in 1 Peter 2:12; Isaiah 10:3; and Luke 19:44.
