Which does the phrase "word nest" in this analogy most likely represent?


"As the marsh-hen secretly builds on the watery sod,

Behold I will build me a nest on the greatness of God:

I will fly in the greatness of God as the marsh-hen flies

In the freedom that fills all the space ’twixt the marsh and the skies"

(from "The Marshes of Glynn" by Sidney Lanier)
