Jeremiah 5:7-8

7“Why should I [overlook these offenses and] forgive you? Your children have abandoned (rejected) Me And sworn [their oaths] by those who are not gods. When I had fed them until they were full [and bound them to Me by a promise], They committed [spiritual] adultery, Assembling in troops at the houses of prostitutes (idols).

8They were like well-fed, lusty stallions, Each one neighing after his neighbor’s wife.
