Ezekiel 47:19
And the south side southward, from Tamar even to the waters of strife in Kadesh, the river to the great sea. And this is the south side southward. And the south side southward, from Tamar even to the waters of strife in Kadesh, the river to the great sea. And this is the south side southward.
Ezekiel 47:19 belongs to the representation of waters issuing from under the threshold of the house eastward at the south side of the altar. They begin as a small, very small rivulet. From that humble beginning they extend to the east country and to the west, to the islands of the sea and to all parts of the world, with power to heal.
The vision means the work is to grow large and spread worldwide. It is not to be centered in any one place. Each institution is to remain independent, working out God's plan under His direction. Burden-bearing in different localities gives strength and development, instead of centralization repressing and weakening powers.
