I was clad with justice: and I clothed myself with my judgment, as with a robe and a diadem.

I put on righteousness, and it clothed me; my justice was as a mantle and a turban.

Righteousness I have put on, and it clotheth me, As a robe and a diadem my justice.

I put on righteousness as my clothing, and was full of it; right decisions were to me a robe and a head-dress.

I put on justice, and I clothed myself with my judgment, like a robe and a diadem.

I put on righteousness - Or "justice" - as a magistrate, and in all his transactions with his fellow-men. It is common to compare moral conduct or traits of character with various articles of apparel; compare Isaiah 11:5, note; Isaiah 61:10, note.
And it clothed me - It was my covering; I was adorned with it. So we speak of being "clothed with humility;" and so, also, of the "garments of salvation."
My judgment - Or rather justice - particularly as a magistrate.
Was as a robe - The word "robe" (מעיל me‛ı̂yl) denotes the "mantle" or outer garment that is worn by an Oriental. It constitutes the most elegant part of his dress; Notes at Isaiah 6:1. The idea is, that his strict justice was to him what the full flowing robe was in apparel. It was that for which he was best known; that by which he was distinguished, as one would be by an elegant and costly robe.
And a diadem - Or, "turban". The word used here צניף tsânı̂yph - is from צנף tsânaph, to roll, or wind around, and is applied to the turban, because it was thus wound around the head. It is applied to the mitre of the high priest Zac 3:5, and may also be to a diadem or crown. It more properly here, however, denotes the "turban," which in the East is an essential part of dress. The idea is, that he was fully clad or adorned with justice.

I put on (l) righteousness, and it clothed me: my judgment [was] as a robe and a diadem.
(l) I delighted to do justice, as others did to wear costly apparel.

I put on righteousness, and it clothed me,.... Not the righteousness of his living Redeemer, the robe of righteousness and garment of salvation he had from him; though he had put on that by faith, and it was his clothing in the sight of God, which covered his person, and covered all his sins from the avenging eye of divine justice; and in which he was presented before God unblamable and irreprovable in his sight, and with which he was adorned and beautified, being made perfectly comely through it, and completely justified by it; but legal righteousness in the administration of his office as a magistrate; he put it on, that is, he exercised it, and he exercised it constantly from morning tonight, and day after day; as a man puts on his clothes in a morning, and keeps them on all the day, and which he is always repeating; and it was as visible in him, and to be seen and observed by all, as the clothes on his back; and it covered him all over as a garment does; no blemish was to be seen in him, or blame to be cast upon him, throughout the whole course of his administration; and this was a fence unto him against all calumny and reproach, as garments are against the inclemency of the weather; see 1-Samuel 12:3; so a godly conversation in the exercise of graces and virtues, and in the performance of duties both to God and man, is sometimes expressed by a putting them on, as garments are put on; see Ephesians 4:24; and these are an outward clothing to appear in before men, and should be shown forth with meekness and wisdom, so as to be beheld by men; and should be continually exercised and constantly performed; and then they are a covering with respect to men, and they appear harmless, blameless, and without rebuke, in the midst of a crooked and perverse generation; and thus, by well doing, put to silence the ignorance of foolish men, and such to the blush, those who falsely accuse their good conversation: and this in every sense was Job's case:
my judgment was as a robe and diadem; such as the high priest among the Jews wore in the execution of his office, which made him look grand and majestic; and it was usual in Job's time, as it is in ours, and has been the custom in all ages and countries, for judges and civil magistrates to be clothed in a different manner from others, as it is proper they should, to command an awe and reverence of them among the common people, and make them respectable to them: but Job did not so much regard his purple robe he was clad in, or the distinguishing turban he wore on his head, or whatever it was, and which might bear some resemblance to a mitre or a diadem; as it was his great concern to administer justice, which he reckoned his greatest honour, and was more ornamental to him than all the showy ensigns of his office; and it was this which gave him honour and esteem among all sorts of men, high and low: and his regard to the poor, before observed, did not arise from a foolish commiseration of them as poor men, and in order to get himself a name for his pity to them, but proceeded upon a principle of justice and equity, which he made the rule of his administration; he did not countenance the poor in his cause right or wrong; not the quality of the person, but the righteousness of his cause, was what he attended to; and he took his part not merely because he was a poor man, but seeing his cause was just.

(Isaiah 61:10; 1-Chronicles 12:18).
judgment--justice.
diadem--tiara. Rather, "turban," "head-dress." It and the full flowing outer mantle or "robe," are the prominent characteristics of an Oriental grandee's or high priest's dress (Zac 3:5). So Job's righteousness especially characterized him.

Put on, &c. - Perhaps he did not wear these: but his steady justice was to him instead of all those ornaments.
