Wisdom - Not the same word as in Proverbs 1:2; better, perhaps, thoughtfulness.
Justice - Rather, righteousness. The word in the Hebrew includes the ideas of truth and beneficence as well as "justice."
Judgment - The teaching of the Proverbs is to lead us to pass a right sentence upon human actions, whether our own or another's.
Equity - In the Hebrew (see the margin) the plural is used, and expresses the many varying forms and phases of the one pervading principle.

To receive the instruction - השכל haskel, the deliberately weighing of the points contained in the teaching, so as to find out their importance.
Equity - משרים mesharim, rectitude. The pupil is to receive wisdom and instruction, the words of wisdom and understanding, justice and judgment, so perfectly as to excel in all. Wisdom itself, personified, is his teacher; and when God's wisdom teaches, there is no delay in learning.

To receive the (c) instruction of wisdom, (d) justice, and judgment, and equity;
(c) To learn to submit ourselves to the correction of those who are wise.
(d) By living justly and rendering to every man that which belongs to him.

To receive the instruction of wisdom,.... Or "prudence" (h); of wise and prudent men; and especially of Christ himself, who bears those names, whose instructions this book is full of; and the design of which is to engage the attention of men to them, and prevail upon them to receive them, and act conformably to them. Which instructions respect the following things; and which are added by way of illustration and amplification, viz.
justice, and judgment, and equity; that which is just in itself, and according to the nature of God and his will; and is judged so by right reason; and is equitable between man and man, and agrees with the law of God. These three, R. Levi Ben Gersom says, signify one and the same thing; true righteousness, doing that which is just to God and man; which the doctrines of grace, or the instructions of wisdom, teach men to do; concerning which many rules may be collected from this book.
(h) "prudentiae", Munster, Vatablus.

To receive . . . of wisdom--For receiving that discipline which discretion imparts. The Hebrew for "wisdom" differs from that of Proverbs 1:2, and denotes rather discreet counsel. Compare the opposite traits of the fool (Proverbs 16:22).
justice . . . equity--all the attributes of one upright in all his relations to God and man.

To receive - Willing to receive the counsels of others. Such as makes men wise and prudent, and to teach just judgments or equity.
