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.

William Gurnall's Christian in Complete Armour: 'The hypocrite does no less than mock God in all his duties. And of all things God can least bear that. God is not mocked. Christ preached this doctrine when he cursed the fig-tree, which did, by her green leaves, mock the passenger, making him come for fruit, and go ashamed without any. Had it wanted leaves as well as fruit, it had escaped that curse. Every lie is a mocking of him to whom it is told, because such a one goes to cheat him, and thereby puts the fool upon him. Why hast thou "mocked me," said Delilah to Samson, "and told me lies?" Judges 16:10, as if she had said—as i…
Matthew Henry: 'When she still continued her importunity (Judges 16:10) he told her that with two new ropes he might be so cramped and hampered that he might be as easily dealt with as any other man, Judges 16:11. This experiment was tried too, but it failed: the new ropes broke from off his arm like a thread, Judges 16:12.'
Hebrew: If you have been following along in the Hebrew text, hopefully you are familiar enough with the vocabulary in these three verses to work through them without much difficulty.
In verse 11, there is a little exercise in the infinitive absolute + imperfect construction.
