Therefore thus saith the LORD; Ask ye now among the heathen, who hath heard such things: the virgin of Israel hath done a very horrible thing.
Ask ye now among the pagan, who hath heard such things? - (Jeremiah 2:10-11.) Even among the pagan it was a thing unheard of that a nation should lay aside its gods for foreign gods, though their gods are false gods. But Israel forsook the true God for foreign false gods.
Virgin of Israel - (2 Kings 19:21). It enhances their guilt, that Israel was the virgin whom God had specially betrothed to Him.
Horrible thing - (Jeremiah 5:30).
