Charles Ellicott Commentary Judges 14:1

"And Samson went down to Timnah, and saw a woman in Timnah of the daughters of the Philistines." — Judges 14:1 (ASV)

To Timnath. —This town, whose site still retains the name Tibneh, is perhaps the same as that in Genesis 38:12, unless that is a town in the mountains of Judah, as Judah is said there to have “gone up” not as here, “down” to it. In Joshua 15:10 it is assigned to Judah but appears to have been afterwards ceded to Dan (Joshua 19:45). The name means “a portion” and is also found in Timnath-serah, where Joshua was buried (Joshua 24:30).

Of the daughters of the Philistines. —This was against the spirit of the law, which forbade intermarriages with Canaanites (Exodus 34:16; Deuteronomy 7:3–4). The sequel showed the wisdom of the law (2 Corinthians 6:14).
