Cross-reference

Deuteronomy 22:21 prescribes death for a woman who plays the whore in her father's house — the concubine returns there after doing so, highlighting the gravity of her sin.

Jeremiah 3:1 uses the same imagery of a wife playing the harlot and leaving her husband, but applies it to Israel's relationship with God — a prophetic parallel.

Genesis 38:24 has a similar accusation of playing the harlot, but Tamar's situation is different — she was seeking justice, not unfaithfulness.

Ezekiel 16:28 uses the same 'played the whore' metaphor for Israel's spiritual unfaithfulness — echoing the literal unfaithfulness here.
