'Dried up' in the Bible

The Lord will divide the gulf of the Egyptian Sea; he will wave his hand over the Euphrates River and send a strong wind, he will turn it into seven dried-up streams, and enable them to walk across in their sandals.

No foreigner who becomes a follower of the Lord should say, 'The Lord will certainly exclude me from his people.' The eunuch should not say, 'Look, I am like a dried-up tree.'"
