And they slew the kings of Midian, beside the rest of them that were slain; namely, Evi, and Rekem, and Zur, and Hur, and Reba, five kings of Midian: Balaam also the son of Beor they slew with the sword. Numbers 31:8
The fate of Balaam was similar to that of Judas, and their characters bear a marked resemblance to each other. Both these men tried to unite the service of God and mammon, and met with signal failure. Balaam acknowledged the true God, and professed to serve Him; Judas believed in Jesus as the Messiah, and united with His followers....Judas expected by his connection with Christ to secure wealth and promotion in that worldly kingdom which, as he believed, the Messiah was about to set up. The failure of his hopes drove him to apostasy and ruin. Both Balaam and Judas had received great light and enjoyed special privileges, but a single cherished sin poisoned the entire character and caused their destruction.
It is a perilous thing to allow an unchristian trait to live in the heart. One cherished sin will, little by little, debase the character, bringing all its nobler powers into subjection to the evil desire. The removal of one safeguard from the conscience, the indulgence on one evil habit, one neglect of the high claims of duty, breaks down the defenses of the soul and opens the way for Satan to come in and lead us astray." (Patriarchs and Prophets, 452)
Reflection: The only safe course for us is to pray daily from a sincere heart as did David, "Hold up my goings in Thy paths, that my footsteps slip not" (Psalm 17:5). (Patriarchs and Prophets, 452)
