Isaiah 5:16 says that God shows his greatness by acting justly and doing what is right, and that his holiness is made known through righteousness. The verse is a contrast: while proud people are brought low, the Lord is lifted up because of his fairness and goodness. The prophet Isaiah speaks these words to the people of Judah and Jerusalem, warning a nation that has turned away from God’s law while assuring them that he remains the holy and righteous judge over all.
But the LORD of Armies is exalted in justice, and God the Holy One is sanctified in righteousness.

What Isaiah 5:16 Means
The verse begins with the idea of being “exalted in justice.” To exalt someone is to lift them up or to show them to be high and worthy of honor. Isaiah says the Lord of Armies, the commander of heaven’s forces, is most clearly seen as great when he deals justly. Justice here means giving each person and each situation its due, setting wrongs right, and refusing to bend the scales for the powerful. God’s power is not shown merely by force but by fairness.
The second half speaks of God the Holy One being “sanctified in righteousness.” To sanctify is to set apart as holy or to honor as holy. Righteousness is living in right relationship with God and others, acting in the way that matches God’s own character. Isaiah is saying that when God’s people and his world reflect what is right, the holiness of God is recognized and respected. The verse does not promise that every injustice will be fixed on our timetable, nor does it guarantee that the righteous will always be safe from trouble. It describes how God’s character is revealed and why his lordship over history is worth trusting.
The Context of Isaiah 5:16
Isaiah was a prophet active in Judah in the late eighth century before Christ, and the book bearing his name records his messages to a nation drifting into complacency and social injustice. The surrounding passage in Isaiah 5:13 to 19 describes the consequences of turning from God: people go into exile for lack of knowledge, the wealthy and the powerful are humbled, and those who mock God’s purposes face judgment. The verse sits in the middle of this warning, offering a turning point where the reader sees that the proud are brought low while God alone is lifted high.
Because the verse follows a description of human pride being humbled, it reads as a reassurance rather than a threat alone. The people of Judah could see their leaders enriching themselves at the expense of the poor, and Isaiah wanted them to understand that the true measure of greatness is God’s justice, not human status. Reading the verse within this sharp contrast helps explain why Isaiah ties God’s exaltation so closely to fairness and right living.
