18 Because the needy will not always be forgotten; the hope of the oppressed will not perish forever. 19 Rise up, Yahveh! Do not allow mere humans to prevail; let the nations be judged in your presence. 20 Put terror in them, Yahveh; let the nations know they are merely humans. Selah
This psalm is a prayer for those who feel forgotten. It is a prayer for justice for those oppressed by powers they cannot control. The psalmist prays for God to act in history as he did to rescue the Israelites from slavery in Egypt.
Independence from tyranny is what God wants for everyone. That is not all he wants, but it is his revealed will.
Lord, rescue those enslaved by tyrants or systems of government which do not allow their people to live and worship freely.
