And he will appoint him captains over thousands, and captains over fifties; and will set them to ear his ground, and to reap his harvest, and to make his instruments of war, and instruments of his chariots.

Wesley's Notes

8:12 Will appoint - Heb. To, or for himself; for his own fancy, or glory, and not only when the necessities of the kingdom require it. And though this might seem to he no incumbrance, but an honour to the persons so advanced, yet even in them that honour was accompanied with great dangers, and pernicious snares of many kinds, which those faint shadows of glory could not recompense; and as to the public, their pomp and power proved very burdensome to the people, whose lands and fruits were taken from them, and bestowed upon these, for the support of their state. Will set them - At his own pleasure, when possibly their own fields required all their time and pains. He will press them for all sorts of his work, and that upon his own terms.

Jamieson-Fausset-Brown Bible Commentary

12. he will appoint him captains-In the East, a person must accept any office to which he may be nominated by the king, however irksome it may be to his taste or ruinous to his interests.

Matthew Henry's Concise Commentary

8:10-22 If they would have a king to rule them, as the eastern kings ruled their subjects, they would find the yoke exceedingly heavy. Those that submit to the government of the world and the flesh, are told plainly, what hard masters they are, and what tyranny the dominion of sin is. The law of God and the manner of men widely differ from each other; the former should be our rule in the several relations of life; the latter should be the measure of our expectations from others. These would be their grievances, and, when they complained to God, he would not hear them. When we bring ourselves into distress by our own wrong desires and projects, we justly forfeit the comfort of prayer, and the benefit of Divine aid. The people were obstinate and urgent in their demand. Sudden resolves and hasty desires make work for long and leisurely repentance. Our wisdom is, to be thankful for the advantages, and patient under the disadvantages of the government we may live under; and to pray continually for our rulers, that they may govern us in the fear of God, and that we may live under them in all godliness and honesty. And it is a hopeful symptom when our desires of worldly objects can brook delay; and when we can refer the time and manner of their being granted to God's providence.
