Esias 26:11

11 O Lord, thine arm is exalted, yet they knew it not: but when they know they shall be ashamed: jealousy shall seize upon an untaught nation, and now fire shall devour the adversaries.

Esias 26:11 In-Context

9 which our soul longs for: my spirit seeks thee very early in the morning, O God, for thy commandments are a light on the earth: learn righteousness, ye that dwell upon the earth.
10 For the ungodly one is put down: no one who will not learn righteousness on the earth, shall be able to do the truth: let the ungodly be taken away, that he see not the glory of the Lord.
11 O Lord, thine arm is exalted, yet they knew it not: but when they know they shall be ashamed: jealousy shall seize upon an untaught nation, and now fire shall devour the adversaries.
12 O Lord our God, give us peace: for thou hast rendered to us all things.
13 O Lord our God, take possession of us: O Lord, we know not other beside thee: we name thy name.
