20 They are like a dream when one awakes; when you arise, Lord, you will despise them as fantasies.

Read Psalm 73:20 Using Other Translations

As a dream when one awaketh; so, O Lord, when thou awakest, thou shalt despise their image.
Like a dream when one awakes, O Lord, when you rouse yourself, you despise them as phantoms.
When you arise, O Lord, you will laugh at their silly ideas as a person laughs at dreams in the morning.
