Psalms 73:26

²⁴ You guide me with Your counsel, and later receive me in glory.

²⁵ Whom have I in heaven but You? And on earth I desire no one besides You.

My flesh and my heart may fail, but God is the strength of my heart and my portion forever.

²⁷ Those far from You will surely perish; You destroy all who are unfaithful to You.

²⁸ But as for me, it is good to draw near to God. I have made the Lord GOD my refuge, that I may proclaim all Your works.

Do read the surrounding verses too, because the context often says more than a single verse.
