Isaiah 1:17

“Learn to do well, &c.] Which men are naturally ignorant of; to do good they have no knowledge; nor can they that are accustomed to do evil learn to do well of themselves; but the Lord can teach them to profit, and of him they should ask wisdom, and desire, under the influence of his grace, to learn to maintain good works for necessary uses, and particularly to do acts of beneficence to all men, and especially to the household of faith; and also, the following ones, seek judgment; seek to do justice between man and man in any cause depending, without respect of persons: relieve the oppressed; the poor that are oppressed by their neighbours that are richer and mightier than they, right their…”

“seek judgment--justice, as magistrates, instead of seeking bribes (Jer 22:3, Jer 22:16). judge--vindicate (Psa 68:5; Jam 1:27).”

“Learn to do well - , To learn here is to become accustomed to, to practice it. To do well stands opposed to all kinds of evil. “Seek judgment.” The word “judgment” - משׁפט mishpâṭ - here means justice. The direction refers particularly to magistrates, and it is evident that the prophet had them particularly in his view in all this discourse. Execute justice between man and man with impartiality. The word “seek” - דרשׁוּ dı̂reshû - means to pursue, to search for, as an object to be gained; to regard, or care for it, as the main thing. Instead of seeking gain, and bribes, and public favor, they were to make it an object of intense interest to do justice. Relieve - - אשׁרוּ 'asherû -…”

“Learn - Begin to live soberly, righteously, and godly. Judgment - Shew your religion to God, by practising justice to men. Judge - Defend and deliver them. Isaiah 1:19”

“1:17 Seeking justice means upholding God’s standards of fairness and advancing the rights of the oppressed, orphans, and widows—those who are weak and marginalized in society (see also Jer 7:5-7; 22:3; Zech 7:10; Matt 23:23; 25:31-46; Jas 1:27).”

“seek: Isa 1:23; Psa 82:3, Psa 82:4; Pro 31:9; Jer 22:3, Jer 22:15, Jer 22:16; Dan 4:27; Mic 6:8; Zep 2:3; Zac 7:9, Zac 7:10, Zac 8:16 relieve: or, righten Isaiah 1:18”

“Five admonitions relating to the practice of what is good: "Learn to do good, attend to judgment, set the oppressor right, do justice to the orphan, conduct the cause of the widow." The first admonition lays the foundation for the rest. They were to learn to do good - a difficult art, in which a man does not become proficient merely by good intentions. "Learn to do good:" hetib is the object to limdu (learn), regarded as an accusative; the inf. abs. הרע in Isa 1:16 takes the place of the object in just the same manner. The division of this primary admonition into four minor ones relating to the administration of justice, may be explained from the circumstance that no other prophet directs so…”
