'Thick' in the Bible

And he said to her, If they only put round me new thick cords which have never been used, then I will become feeble and will be like any other man.

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.
