water flowed out like rivers, as if the rock itself was changed
into water; and which came a constant and continual supply for

Numbers
20:11 ) ( Psalms 78:15
Psalms
78:16 ) ( 105:41 ) (
1
Corinthians 10:4 ) .

him; is the fountain of it, from whence it flows in great
abundance for the supply of his people's wants, while passing
through this wilderness to Canaan's land.
