The Ark of Testimony (Ex.25:10-22) is a type (resemblance) for Virgin Mary because firstly, the Ark was overlaid with gold
on the inside and the outside, symbolising her purity and elevation. Secondly because the Ark was made of Acacia wood which does not decay, symbolising her sanctity. Thirdly because the Ark contained the manna, which symbolises Christ the Living Bread who came down from heaven, and lastly because the Ark contained the two tablets of the Law which symbolise Christ the Word of God (John.1: 1). The ladder reaching from earth to heaven which Jacob saw in his dream, is a type (resemblance) for Virgin Mary. Being this conjunction between earth and heaven in the Incarnation of Christ; She was the earth in which heaven dwelt and whilst she was on earth she bore heaven within her (Gen.28: 12).
The burning bush that was not consumed and which Moses saw (Ex.3), is a type (resemblance) for Virgin Mary, upon whom came the Holy Spirit with His Divine fire and she was not consumed.
