4. Those are brought into slavery who were a free people, and not only their own masters, but masters of all about them, and this is as much as any thing their reproach (v. 5): Our necks are under the grievous and intolerable yoke of persecution (the iron yoke which Jeremiah foretold should be laid upon them, Jer. xxviii. 14); we are used like beasts in the yoke, that wholly serve their owners, and are at the command of their drivers. That which aggravated the servitude was, (1.) That their labours were incessant, like those of Israel in Egypt, who were daily tasked, nay, overtasked: We labour and have no rest, neither leave nor leisure to rest. The oxen in the yoke are unyoked at night and have rest; so they have, by a particular provision of the law, on the sabbath day; but the poor captives in Babylon, who were compelled to work for their living, laboured and had no rest, no night's rest, no sabbath-rest; they were quite tired out with continual toil. (2.) That their masters were insufferable (v. 8): Servants have ruled over us; and nothing is more vexatious than a servant when he reigns, Prov. xxx. 22. They were not only the great men of the Chaldeans that commanded them, but even the meanest of their servants abused them at pleasure, and insulted over them; and they must be at their beck too. The curse of Canaan had now become the doom of Judah: A servant of servants shall he be. They would not be ruled by their God, and by his servants the prophets, whose rule was gentle and gracious, and therefore justly are they ruled with rigour by their enemies and their servants. (3.) That they saw no probable way for the redress of their grievances: "There is none that doth deliver us out of their hand; not only none to rescue us out of our captivity, but none to check and restrain the insolence of the servants that abuse us and trample upon us," which one would think their masters should have done, because it was a usurpation of their authority; but, it should seem, they connived at it and encouraged it, and, as if they were not worthy of the correction of gentlemen, they are turned over to the footmen to be spurned by them. Well might they pray, Lord, consider and behold our reproach.
