17 Neither shall he multiply wives to himself. Polygamy at that time had generally prevailed, so that the very humblest of the people violated the marriage vow with impunity; and therefore it was necessary that the kings should be bound with closer restrictions, lest by their example they should give greater countenance to incontinency. And thus their ignorance is easily refuted who conclude that what was specially interdicted to the kings was permitted to private individuals, whereas the law of chastity was imposed upon the former, because without this remedy there would be no bounds to their lasciviousness. Besides, the people would have been subjected to great expense on their account, since such is the ambition of women, that they would all have desired to receive royal treatment, and would have even vied with each other in finery, as actually came to pass. David transgressed this law, and in some degree excusably on account of his repudiation by Michal; still it appears that lust had more power over him than the continency prescribed by God. What follows is so connected by some as if it were the reason of the foregoing sentence, in this way, “that kings were not to multiply wives to themselves, lest their heart should turn away from what was right,” as was the case with Solomon; for, from being too devoted to his wives, and being deceived by the snares of women, he fell into idolatry. And assuredly it can scarcely fail to happen, that when many wives beset a man, they must render his mind effeminate, and stifle in him all his manly good sense. Yet I prefer taking the clause separately, that kings must beware lest the splendor of their dignity should affect the soundness of their judgment, for nothing is more difficult than for one in great power to continue disposed to temperance. Therefore God does not in vain enjoin that they should constantly persevere in their duty, and not lose their understanding. Moreover, He forbids kings to heap up treasures, because it cannot be done without rapine and violent exactions; whilst, at the same time, wealth encourages them audaciously to undertake unjust wars, incites them to gross dissipation, and at length hurries them forward to tyrannical excesses. First, therefore, God would have kings beware, lest in their pursuit of riches they should exhaust the blood of the people, and lest they should lavish their ill-gotten money in superfluous expenses, and be extravagant with what belongs to others; and lastly, lest they should be tempted by the pride of wealth to attempt unlawful things.
