Jamieson, Fausset and Brown on Judges 16:13

13. If thou weavest the seven locks of my head--braids or tresses, into which, like many in the East, he chose to plait his hair. Working at the loom was a female employment; and Delilah's appears to have been close at hand. It was of a very simple construction; the woof was driven into the warp, not by a reed, but by a wooden spatula. The extremity of the web was fastened to a pin or stake fixed in the wall or ground; and while Delilah sat squatting at her loom, Samson lay stretched on the floor, with his head reclining on her lap--a position very common in the East.
