The psalm opens with a double question: who shall sojourn in your tent? Who shall dwell on your holy hill? It refers to the temple in Jerusalem, the place where God drew near to his people.
The answer is a list of character traits. It is the one who walks blamelessly, does what is right and speaks truth in his heart. He does not slander with his tongue, do evil to his neighbor or take up a reproach against his friend. He despises a vile person but honors those who fear the Lord. He keeps his oath even when it hurts and does not change.
He also does not put out his money at interest, that is, he does not exploit the needy, and he does not take a bribe against the innocent. The psalm ends with a promise: the one who does these things shall never be moved, which means he will stand firm in God's presence.
