Verse 10:[1] And Delilah said unto Samson, Behold, thou hast mocked me, and told me lies: now tell me, I pray thee, wherewith thou mightest be bound.
[Thou hast mocked me, הֵתַ֣לְתָּ בִּ֔י] Thou hast deceived me; thou hast lied to me (Vatablus). It is sufficiently clear from this that Samson was not aware of the ambush: and it is likely that she indicated that she wished to test him, whether or not he had spoken true things, and had turned the whole matter into laughter (Bonfrerius).
Verse 11:[2] And he said unto her, If they bind me fast with new ropes that never were occupied (Heb. wherewith work hath not been done[3]), then shall I be weak, and be as another man.
[If I shall be bound] Hebrew: If binding they shall bind me,[4] that is, they shall most carefully bind me fast (Vatablus). If…they restrain. It is an impersonal speech (Piscator).
[With cords, בַּעֲבֹתִים[5]] In ropes (Malvenda). It signifies thicker cords consisting of three (Drusius).
Verse 12:[6] Delilah therefore took new ropes, and bound him therewith, and said unto him, The Philistines be upon thee, Samson. And there were liers in wait abiding in the chamber. And he brake them from off his arms like a thread.
