Albert Barnes Commentary Judges 16:5

"And the lords of the Philistines came up unto her, and said unto her, Entice him, and see wherein his great strength lieth, and by what means we may prevail against him, that we may bind him to afflict him: and we will give thee every one of us eleven hundred [pieces] of silver." — Judges 16:5 (ASV)

And the lords of the Philistines - See Judges 3:3 note.

His great strength lies - Rather, “where his strength is great.”

Eleven hundred pieces of silver - The greatness of the bribe offered to Delilah, 5,500 shekels of silver, nearly two talents (Exodus 38:24, note), shows the importance attached to Samson’s capture.
