12, 13. (a) In what way is there no helper for Jehovah? (b) How does Jehovah’s arm furnish salvation, and how does his rage support him?

¹² Jehovah continues: “I kept looking, but there was no helper; and I began to show myself astonished, but there was no one offering support. So my arm furnished me salvation, and my rage was what supported me. And I kept stamping down peoples in my anger, and I proceeded to make them drunk with my rage and to bring down to the earth their spurting blood.”​—Isaiah 63:5, 6.

¹³ No human helper can claim credit for Jehovah’s grand day of vengeance. Nor does Jehovah need any human support to carry out his will.c His immeasurably powerful arm of strength is sufficient for the task. (Psalm 44:3; 98:1; Jeremiah 27:5) Moreover, his rage supports him. How? In that God’s rage is not uncontrolled emotion but righteous indignation. Since Jehovah always acts on the basis of righteous principles, his rage supports and motivates him in bringing “down to the earth” the “spurting blood” of his enemies, to their humiliation and defeat.​—Psalm 75:8; Isaiah 25:10; 26:5.
