Each time Delilah tested Samson's strength, what did she call out to him?

Answer: The Philistines have come!

Each time she cried, "Samson, the Philistines are here!" (KJV: "The Philistines be upon thee, Samson").

“While the men were hidden in her room, she called out, “Samson, the Philistines are here!” But he snapped the bowstrings like a strand of yarn seared by a flame. So the source of his strength remained unknown.”— Judges 16:9 (BSB)
