SIR EDWARD BURNE-JONES
And he dreamed,and behold a ladder set up on the earth,and the top of it reached to heaven:and behold the angels of God ascending and descending on it.Genesis 28:12 RVAnd he said,Hear now my words:if there be a prophet among you,I the LORD will make myself known unto him in a vision,I will speak with him in a dream.Numbers 12:6 RVIn a dream,in a vision of the night,when deep sleep falleth upon men,in slumberings upon the bed;Job 33:15 RV
It struck me that these three may be related. Dreams are mentioned frequently in the OT, but usually it is God speaking to someone in a dream.
These three are visions within a dream.
