What was implied in Lamentations 2:1–3 becomes explicit in these verses. God has become like an enemy.
The writer is making a comparison by using the expression like.
God is not unequivocally and absolutely their enemy, for then there would be no possibility of hope. Still, the severity of his enmity is not downplayed.1 This is evident from the use of the divine warrior metaphors that have occured earlier in Lamentations.2 God not only delivered his people to the enemy, he came forward himself as an enemy.
4 Il a tendu son arc comme un ennemi; Sa droite s'est dressée comme celle d'un assaillant; Il a fait périr tout ce qui plaisait aux regards; Il a répandu sa fureur comme un feu sur la tente de la fille de Sion.
