John Gill's Exposition of the Whole Bible
Ecclesiastes 12:10
The preacher sought to find out acceptable words,.... Not mere words, fine and florid ones, the words which man's wisdom teacheth, an elegant style, or eloquent language; not but that it is proper for a preacher to seek out and use words suitable and apt to convey right ideas to the minds of men of what he says; but doctrines are rather here meant, "words of desire", "delight", and "pleasure" d, as the phrase may be rendered; even of God's good will and pleasure, so Alshech; for the same word is sometimes used of God in this book and elsewhere: see Ecclesiastes 3:1; and so may take in the doctrine of God's everlasting love to his people, and his delight and pleasure in them; of his good will towards them in sending Christ to suffer and die for them, and save them; in pardoning their sins through his blood, in which he delights; in regenerating and calling them by his grace, and revealing the things of the Gospel to them, when he hides them from others, which is all of his own will and pleasure, and as it seems good in his sight: or words and doctrines, which are desirable, pleasing, and acceptable unto men; not that Solomon did, or preachers should, seek to please men, or seek to say things merely for the sake of pleasing men, for then they would not be the servants of Christ; nor are the doctrines of the Gospel pleasing to carnal men, but the reverse: they gnash their teeth at them, as Christ's hearers did at him; the preaching of a crucified Christ is foolishness, and the things of the Spirit of God are insipid things, to natural men; they are enemies to the Gospel: but to sensible sinners they are very delightful, such as peace, pardon, righteousness, and salvation, by Christ, 1 Timothy 1:15; for the worth of them, they are more desirable to them than gold and silver, and are more delightful to the ear than the best of music, and more acceptable to the taste than honey or the honeycomb, Psalms 19:10;
and [that which was] written [was] upright; meaning what was written in this book, or in any other parts of Scripture, which the preacher sought out and inculcated; it was according to the mind and will of God, and to the rest of the sacred word; it was sincere, unmixed, and unadulterated with the doctrines and inventions of men; it showed that man had lost his uprightness, had none of himself, and where it was to be had, even in Christ; and was a means of making men sound, sincere, and upright at heart; and of directing them to walk uprightly, and to live soberly, righteously, and godly, in the world;
[even] words of truth; which come from the God of truth, that cannot lie, as all Scripture does; of which Christ, who is the truth, is the sum and substance; and which are inspired by the Spirit of truth, and led into by him, and made effectual to saving purposes; and which holds good of the whole Scripture, called the Scripture of truth, Daniel 10:1; and of the Gospel, which is the word of truth, and of every doctrine of it, John 17:17.
