“You multiplied

Your prostitute ways

With Chaldea,

The land or merchants.

Even with this

You were not satisfied.”

Yahweh said that they multiplied their prostituting ways with the Chaldeans, the Babylonians, who would later take them over. However, they were originally attracted to them by their merchandise, since the Chaldeans were good merchants. Even this mercantile arrangement was not enough. Jerusalem was never satisfied.
