Charles H. Spurgeon on Psalms 15:4

"In whose eyes a vile person is contemned," etc. When wicked Jehoram, king of Israel, came to Eliseus, the prophet, to ask counsel of the Lord, and to entreat for waters, having in company Jehoshaphat, the king of Judah, being virtuous; the prophet showeth his contempt to the one, being wicked, and his reverence to the other, being godly, faithful and virtuous, said, "As the Lord of hosts liveth, before whom I stand, were it not that I regard the presence of Jehoshaphat, the king of Judah, I would not look toward thee, nor see thee." 2 Kings 3:14. Thus was the wicked vile in his sight; thus did he not flatter the ungodly. In like manner godly Mordecai, the Jew, having Haman the ambitious and proud Agagite in contempt, would in no wise bow the knee unto him in sign of honour, as the rest of the people did; for which cause he was extremely hated, menaced, and molested of proud and wicked Haman. To wink at their wickedness, to uphold them in their iniquity, to fawn upon them and flatter them, to praise them when they deserve just reproof, is, as it were, an honouring of them; to which, as to a most grievous sin, the prophet denounces a most bitter curse: "Woe unto them that call evil good, and good evil; that put darkness for light, and light for darkness; that put bitter for sweet, and sweet for bitter!" Isaiah 5:20. Richard Turnbull.
