2 In that day shall the branch of the Lord be beautiful and glorious; the fruit of the earth excellent and comely to them that are escaped of Israel.
When Jacob, who was called Israel, blessed his sons, he gave the following blessing to Joseph who saved his family from famine by being obedient to the Lord (Gen. 49):
22 Joseph is a fruitful bough, even a fruitful bough by a well; whose branches run over the wall
In the last days, Israel would be the family of the believers, and those who would inherit the blessing of Joseph, of his sons Ephraim and Manasseh, would be a "multitude of nations" and would bless the earth through their faithfulness. As believers we have the challenge to be fruitful, which we can do if we are close to the well of living waters.
