Esias 63:5

5 And I looked, and there was no helper; and I observed, and none upheld: therefore my arm delivered them, and mine anger drew nigh.

Esias 63:5 In-Context

3 I am full of trodden , and of the nations there is not a man with me; and I trampled them in my fury, and dashed them to pieces as earth, and brought down their blood to the earth.
4 For the day of recompence has come upon them, and the year of redemption is at hand.
5 And I looked, and there was no helper; and I observed, and none upheld: therefore my arm delivered them, and mine anger drew nigh.
6 And I trampled them in mine anger, and brought down their blood to the earth.
7 I remembered the mercy of the Lord, the praises of the Lord in all things wherein he recompenses us. The Lord is a good judge to the house of Israel; he deals with us according to his mercy, and according to the abundance of his righteousness.
