Proverbs 31 exhorts mercy and compassion to those less fortunate. It also contains advice regarding a capable wife, who is worth more than wealth. She is able to work inside or outside the home with equal success. She teaches her children with wisdom. It is more important to marry a woman who fears the Lord than one that is simply beautiful but does not have the Lord in her life.
Psalm 94 is a call to the Lord for vengeance. It acknowledges that God cares for the writer and will hold him up. It desires that God punish those who are bringing him harm.
