But the liberal shall devise liberal things. We have already said that these statements of the Prophet have a deeper meaning than is commonly supposed; for he does not speak in the ordinary sense of the words, but treats of the reformation of the Church. This relates therefore to the regenerate, over whom Christ reigns; for, although all are called by the voice of the gospel, yet there are few who suffer themselves to be placed under his yoke. The Lord makes them truly kind and bountiful, so that they no longer seek their own convenience, but are ready to give assistance to the poor, and not only do this once or oftener, but every day advance more and more in kindness and generosity. In acting liberally he shall make progress. This passage is commonly explained in a different manner, namely, that the liberal advance themselves, and become great by doing good; because God rewards them, and bestows on them greater blessings. This view pleases at first sight; but the Prophet, on the contrary, shews that the liberal will never cease to perform acts of generosity, for they will daily make greater progress, and will pursue the same designs and adhere firmly to their intention, as it is said by the Psalmist, "He hath dispersed, he hath given to the poor; his righteousness endureth for ever." (Psalm 112:9; 2-Corinthians 9:9.) This is added, because it is easy to counterfeit liberality for a time; many even think that they are sincerely bountiful because they have performed an act of beneficence, but quickly cease and change their purpose. But true liberality is not momentary or of short duration. They who possess that virtue persevere steadily, and do not exhaust themselves in a sudden and feeble flame, of which they quickly afterwards repent. This is what the Prophet intended to express by the word qvm, (kum,) which signifies to "arise" and "grow." There are indeed many occurrences which retard the progress of our liberality. We find in men strange ingratitude, so that what we give appears to be ill bestowed. Many are too greedy, and, like horse-leeches, suck the blood of others. But let us remember this saying, and listen to Paul's exhortation "not to be weary in well-doing;" for the Lord exhorts us not to momentary liberality, but to that which shall endure during the whole course of our life. (Galatians 6:9.)

But the liberal - This seems also to have the force of a proverbial expression. The word 'liberal' means generous, noble, large-hearted, benevolent; a man of large views and of public spirit; a man above covetousness, avarice, and self-seeking; a man who is willing to devote himself to the welfare of his country, and to the interests of his fellow-men. It is implied here that such persons would be selected to administer the affairs of the government I under the wise and virtuous prince of whom the prophet speaks.
Deviseth liberal things - He purposes those things which will tend to promote the public welfare, and not those merely which will conduce to his private ends and gratification.
And by liberal things shall he stand - Margin, 'Be established.' That is, according to the connection, he shall be confirmed, or approved in the government of the virtuous king referred to. It is, however, a proposition in a general form, and means also that a man by a liberal course shall be established; that is, his character, reputation, hopes, shall be established by it. This is true now. If a man wishes to obtain permanent peace and honor, the esteem of his fellow-men, or the evidence of divine approbation, it can be best done by large and liberal schemes to advance the happiness of a dying world. He who is avaricious and narrow-minded has no happiness, and no durable reputation; he who is large-hearted and benevolent, has the approbation of the wise and good, the favor of God, and a firm and unshaken support in the trials of life, and in the agonies of death.

Liberal things "Generous purposes" - "Of the four sorts of persons mentioned Isaiah 32:5, three are described, Isaiah 32:6, Isaiah 32:7, and Isaiah 32:8, but not the fourth." - Secker. Perhaps for והוא vehu, and he, we ought to read ושוע veshoa, the bountiful.

But the liberal man deviseth liberal things,.... The man of a princely spirit consults and contrives, and delivers out things worthy of a prince and governor in the church of God; he that is one of a free spirit, that is made free by the Spirit of God, and is led into the doctrines of free grace, will study to deliver out the same to others, and, as he has freely received, he will freely give, and without any sinister, selfish, and mercenary ends and views:
and by liberal things shall he stand; or, "be established" (i); both by the doctrines of free grace he dispenses to others, to be established by and with which is a good thing; and by the free communications of the gifts and grace of the Spirit to him, to supply and furnish him yet more and more for his work; by the discoveries of the free favour of God unto him; by the enjoyment of his gracious presence in private and in public; by the blessings of a free and well ordered covenant; and, at last, by being brought to eternal glory and happiness, in which he will be settled to all eternity; or, "on liberal things shall he stand"; grace here, and glory hereafter. The Targum is,
"the righteous consult truth, and they upon truth shall stand.''
(i) "stabilietur", Gataker.

liberal--rather, "noble-minded."
stand--shall be approved under the government of the righteous King.
