The people took their dough. They probably regarded dough as more convenient for a journey than flour, and so made their flour into dough before starting; but they had no time to add leaven. Their kneading-troughs.
This rendering is correct, both here and in the two other places where the word occurs (Exodus 8:3, and Deuteronomy 28:5). Kneading-troughs would be a necessity in the desert, and, if like those of the modern Arabs, which are merely small wooden bowls, would be light and portable.
The dough and kneading-troughs, with perhaps other necessaries, were carried, as the Arabs still carry many small objects, bound up in their clothes (i.e; in the beged or ample shawl) upon their shoulders.
