Albert Barnes Commentary Exodus 12:34

"And the people took their dough before it was leavened, their kneading-troughs being bound up in their clothes upon their shoulders." — Exodus 12:34 (ASV)

Kneadingtroughs - (Compare the marginal note and Deuteronomy 28:5). The troughs were probably small wooden bowls in which the cakes when baked were preserved for use. The Hebrews used their outer garment, or mantle, in the same way as the Bedouins currently do, who make a bag of the voluminous folds of their burnous. See Ruth 3:15; 2 Kings 4:39.
