And they made their lives bitter with hard bondage,.... So that they had no ease of body nor peace of mind; they had no comfort of life, their lives and mercies were embittered to them: in mortar and in brick, and in all manner of service of the field; if Pelusium was one of the cities they built, that had its name from clay, the soil about it being clayish, and where the Israelites might be employed in making brick for the building of that and other cities: Josephus (d) says, they were ordered to part the river (Nile) into many canals, to build walls about cities, and raise up mounds, lest the water overflowing the banks should stagnate; and to build pyramids, obliging them to learn various arts, and inure themselves to labour: so Philo the Jew says (e), some worked in the clay, forming it into bricks, and others in carrying straw: some were appointed to build private houses, others the walls of cities, and to cut ditches and canals in the river, and obliged day and night to carry burdens, so that they had no rest, nor were they suffered to refresh themselves with sleep; and some say that they were not only employed in the fields in ploughing and sowing and the like, but in carrying of dung thither, and all manner of uncleanness: of their being employed in building of pyramids and canals; see Gill on Gen 47:11. all their service wherein they made them serve was with rigour; they not only put them to hard work, but used them in a very churlish and barbarous manner, abusing them with their tongues, and beating them with their hands: Philo in the above place says, the king not only compelled them to servile works, but commanded them heavier things than they could bear, heaping labours one upon another; and if any, through weakness, withdrew himself, it was judged a capital crime, and the most merciless and cruel were set over them as taskmasters.
