Balaam: The Error of Gain Through Worngdoing

^{Jude 1:10-25 KJV
10} But these speak evil of those things which they know not: but what they know naturally, as brute beasts, in those things they corrupt themselves.
¹¹ Woe unto them! for they have gone in the way of Cain, and ran greedily after the error of Balaam for reward, and perished in the gainsaying of Core.
¹² These are spots in your feasts of charity, when they feast with you, feeding themselves without fear: clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit, twice dead, plucked up by the roots;
¹³ Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.
¹⁴ And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,
¹⁵ To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him.
¹⁶ These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men's persons in admiration because of advantage.
¹⁷ But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ;
¹⁸ How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts.
¹⁹ These be they who separate themselves, sensual, having not the Spirit.
²⁰ But ye, beloved, building up yourselves on your most holy faith, praying in the Holy Ghost,
²¹ Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.
²² And of some have compassion, making a difference:
²³ And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh.
²⁴ Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,
²⁵ To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen.
  
I think Balaam's error was gain through wrongdoing.  I think we can get the gifts of God through an upright life before God and man.  We ought to praise God for everything He does because He ordained it.  He faithful and just to His people.

Psalm 125:4
LORD, do good to those who are good, to those who are upright in heart.
Proverbs 2:7
He holds success in store for the upright, he is a shield to those whose walk is blameless,
