Psalm 94 Feb. 23  1Yahweh, You God to whom alone vengeance belongs, You God to whom vengeance belongs, shine forth. 2Rise up, You judge of the earth, repay the proud what they deserve. 3Yahweh, how long will the wicked, how long will the wicked triumph? 4They pour out arrogant words; all the evildoers boast. 5They break Your people in pieces, Yahweh, and afflict Your heritage. 6They kill the widow and the alien, and murder the fatherless. 7They say, Yah will not see, neither will Jacob’s God consider. 8Consider, you senseless among the people; you fools, when will you be wise? 9He who implanted the ear, won’t He hear? He who formed the eye, won’t He see? 10He who disciplines the nations, won’t He punish? He who teaches man knows; 11Yahweh knows the thoughts of man, that they are futile. 12Blessed is the man whom You discipline, Yah, and teach out of Your law; 13that You may give him rest from the days of adversity, until the pit is dug for the wicked. 14For Yahweh won’t reject His people, neither will He forsake His inheritance. 15For justice will return to the righteous, and all the upright in heart shall follow it. 16Who will rise up for me against the wicked? Who will stand up for me against the evildoers? 17Unless Yahweh had been my help, my soul would have soon been silenced. 18When I said, My foot is slipping! Your grace, Yahweh, held me up. 19In the multitude of my thoughts within me, Your comforts delight my soul. 20Shall the throne of wickedness have fellowship with You, which brings about mischief by statute? 21They gather themselves together against the soul of the righteous, and condemn the innocent blood. 22But Yahweh has been my high tower, my God, the rock of my refuge. 23He has brought on them their own iniquity, and will cut them off in their own wickedness. Yahweh, our God, will cut them off.   

Commentary

94:1 David sees Yahweh as the God of revenge, the one alone to whom vengeance belongs. Our response to this is to believe that truly vengeance is God’s and therefore we will not avenge ourselves (Rom. 12:19). I take this to apply to all the micro-level ‘takings of vengeance’ which we so easily do in our words, body language, attitudes etc., in response to the hurt received from others. 
94:9 One implication of believing that we were created by God as a special, purposefully designed creation is that we will believe that God sees and knows all things; the designer of the eyes and ears which we have 24/7 can surely see and hear everything going on in our lives.
94:12 True hearkening to the word is a chastening experience. It isn't easy; not as easy as reading a book called the Bible and going through the process of interpretation. Our sufferings make sense and are worked through by God insofar as we are open to and aware of His word; for they are designed to assist us in our being conformed to His word.
