Charles Ellicott Commentary Jeremiah 18:13

"Therefore thus saith Jehovah: Ask ye now among the nations, who hath heard such things; the virgin of Israel hath done a very horrible thing." — Jeremiah 18:13 (ASV)

Ask ye now among the heathen. —The appeal of Jeremiah 2:10-11 is renewed. Judah had not been true, even as heathen nations were true, to its inherited faith and worship. The virgin daughter of Israel (Isaiah 1:8; Jeremiah 14:17)—the epithet is emphasised, as contrasted with the shame that follows—had fallen from a greater height to a profounder depth of debasement.
