Judges 16:1

Then went Samson to Gaza, and saw there an harlot, and went in unto her.

Cross-reference

In 1 Corinthians 6:16, Paul says joining with a prostitute makes one body — exactly what Samson does here, illustrating the principle.

In Joshua 10:41, Gaza was conquered by Joshua; Samson's visit to a Philistine-controlled Gaza shows the failure to fully possess the land.

In Joshua 15:47, Gaza is assigned to Judah; Samson's visit to a Philistine city highlights the incomplete conquest.

Proverbs 7:8 depicts a young man approaching a prostitute's house — similar to Samson's action, though Proverbs warns against it.
