to dry up: for water to fail and a wet place to go dry
This is the word for water disappearing. A flood recedes, a river runs out, a sea is held back, and the bed that held the water is left dry. The picture is the loss of the water itself, and with it the loss of the life that the water supported.
Most often the one drying things up is God. He dries the waters of the flood, rebukes the sea and turns it dry, and threatens to reduce rivers and pools to dust as an act of judgment. The same act can be rescue or ruin depending on who is standing in the dry place. In a few passages a proud king boasts that he has dried up rivers under his own feet, claiming a power that belongs to God alone.
A closely related Hebrew verb (yavesh) also means "to be dry," and the two often stand side by side. This word leans toward the drying up of standing water, where the other can describe ground, plants, or bones going dry.
