Aber er ist weise und bringt doch Unheil und sein Wort nimmt er nicht zurück. Er steht auf wider das Haus der Frevler, wider den Beistand der Übeltäter.

Generally a person who resolves to set about a matter, accompanies his resolve by rising, hence the verb is employed to express “to resolve” to do a certain thing; as, “That my son hath stirred up my servant against me” (1 Sam. 22:8). The word is figuratively used to signify the execution of a divine decree against a people sentenced to extermination, as “And I will rise against the house of Jeroboam” (Amos 7:9); “but he will arise against the house of the evildoers” (Isa. 31:2). Possibly in Psalm 12:6 the verb has this latter sense, as also in Psalm 102:13, namely: Thou wilt rise up against her enemies.
