Adam Clarke Bible Commentary
The task-masters of the people and their officers - The task-masters were Egyptians, (see Clarke on Exo 1:11 (note)), the officers were Hebrews; see Clarke below Exo 5:14 (note). But it is probable that the task-masters Exo 1:11, who are called שרי מסים sarey missim, princes of the burdens or taxes, were different from those termed taskmasters here, as the words are different; נגשים nogesim signifies exactors or oppressors - persons who exacted from them an unreasonable proportion either of labor or money.
Officers - שטרים shoterim; those seem to have been an inferior sort of officers, who attended on superior officers or magistrates to execute their orders. They are supposed to have been something like our sheriffs.
Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary
As Pharaoh possessed neither fear of God (εὐσέβεια) nor fear of the gods, but, in the proud security of his might, determined to keep the Israelites as slaves, and to use them as tools for the glorifying of his kingdom by the erection of magnificent buildings, he suspected that their wish to go into the desert was nothing but an excuse invented by idlers, and prompted by a thirst for freedom, which might become dangerous to his kingdom, on account of the numerical strength of the people. He therefore thought that he could best extinguish such desires and attempts by increasing the oppression and adding to their labours. For this reason he instructed his bailiffs to abstain from delivering straw to the Israelites who were engaged in making bricks, and to let them gather it for themselves; but yet not to make the least abatement in the number (מתכּנת) to be delivered every day. בּעם הנּגשׂים, "those who urged the people on," were the bailiffs selected from the Egyptians and placed over the Israelitish workmen, the general managers of the work. Under them there were the שׁטרים (lit., writers, γραμματεῖς lxx, from שׁטר to write), who were chosen from the Israelites (vid., Exo 5:14), and had to distribute the work among the people, and hand it over, when finished, to the royal officers. לבנים לבן: to make bricks, not to burn them; for the bricks in the ancient monuments of Egypt, and in many of the pyramids, are not burnt but dried in the sun (Herod. ii. 136; Hengst. Egypt and Books of Moses, pp. 2 and 79ff.). קשׁשׁ: a denom. verb from קשׁ, to gather stubble, then to stubble, to gather (Num 15:32-33). תּבן, of uncertain etymology, is chopped straw; here, the stubble that was left standing when the corn was reaped, or the straw that lay upon the ground. This they chopped up and mixed with the clay, to give greater durability to the bricks, as may be seen in bricks found in the oldest monuments (cf. Hgst. p. 79).
Jamieson-Fausset-Brown Bible Commentary
Pharaoh commanded--It was a natural consequence of the high displeasure created by this interview that he should put additional burdens on the oppressed Israelites.
taskmasters--Egyptian overseers, appointed to exact labor of the Israelites.
officers--Hebrews placed over their brethren, under the taskmasters, precisely analogous to the Arab officers set over the Arab Fellahs, the poor laborers in modern Egypt.
John Gill Bible Commentary
And Pharaoh commanded the same day the taskmasters of the people,.... Who were Egyptians, and whom Pharaoh sent for the same day, to give them orders to oppress them yet more and more, so far was he from complying with their request:
and their officers; who were Israelites, and were under the taskmasters, and accountable to them for each man's work that they had the inspection and care of:
saying, as follows.
Tyndale Open Study Notes
5:6-14 Pharaoh made the work harder in retaliation for their insubordination; he also believed they had too much time on their hands (5:8). He could not conceive of a god who would reveal himself outside of the established royal system of worship, so the only explanation he could imagine for their strange religious ideas was that they had dreamed them up themselves—when they should have been working (see also 5:17).
