Isaiah 11:4 in the King James Version
But with righteousness shall he judge the poor, and reprove with equity for the meek of the earth: and he shall smite the earth with the rod of his mouth, and with the breath of his lips shall he slay the wicked.
Context
3 His delight will be in the fear of the LORD. He will not judge by the sight of his eyes, neither decide by the hearing of his ears;
4 but he will judge the poor with righteousness, and decide with equity for the humble of the earth. He will strike the earth with the rod of his mouth; and with the breath of his lips he will kill the wicked.
5 Righteousness will be the belt around his waist, and faithfulness the belt around his waist.
