This book is a study of the various metaphors, figures, similes, and usages of water found in the book of Isaiah. It covers representations of water relating to: water as a blessing in nature; the sea as a symbol of the expanse of space; Yahweh, the rider of the clouds; water or absence of water as symbol of divine punishment, hardships, and affliction; water as a defense strategy in military circumstances; water as a means of dilution; rain and snow as symbols of Yahweh’s word; various forms of water symbolizing arrogance; rain, streams, water, and snow as symbols of forgiveness; water as a metaphor for Yahweh’s control over nations and triumph over enemies; calm water as a symbol of trust in Yahweh; Yahweh’s knowledge as waters cover the sea; water, lack of water, and overcoming threatening water as metaphors or similes for restoration and help; the great river as a symbol of the influx of nations; tears as the manifestation of lament and mourning; dew as a symbol of serenity and life-giving power; the personification of water; troubled waters as a symbol of the wicked; swimming as desperate effort to survive; and cultic practices involving water.

These themes emphasize important religious truths in the book of Isaiah. They include many concepts dealing with the nature and mighty acts of Yahweh; sin, punishment and forgiveness; Yahweh’s work over and through nations; personal and corporate matters like trust and lament; and Yahweh’s work in nature.
