Mark 4:40

And he said unto them, 

Why are ye so fearful? 

how is it that ye have no faith?

Pillar

And when the cloud 

was taken up from 

over the tabernacle, 

the children of Israel 

went onward in 

all their journeys: 

But if the cloud were 

not taken up, then they 

journeyed not till the day 

that it was taken up. 

For the cloud of the Lord 

was upon the tabernacle by 

day, and fire was on it by 

night, in the sight of all 

the house of Israel, 

throughout all their journeys.
