'Knotting' in the Bible

And they said, No; we will take you and give you up into their hands, but truly we will not put you to death. So knotting two new cords round him they took him up from the rock.

So Delilah took new thick cords, knotting them tightly round him, and said to him, The Philistines are on you, Samson. And men were waiting secretly in the inner room. And the cords were broken off his arms like threads.
