Final answer:
In Hosea 4:15, the term 'harlot' is used metaphorically to describe the Israelites' spiritual infidelity and idolatrous practices.
Step-by-step explanation:
In the Bible, the term 'harlot' is often used metaphorically to describe a faithless or idolatrous people rather than referring to specific individuals. In Hosea 4:15, the prophet Hosea is speaking to the Israelites, accusing them of playing the harlot and forsaking God. It is used as a metaphor for their spiritual infidelity and idolatrous practices.
