G2047–ἐρημία–erēmia

And his disciples say unto him, Whence should we have so much bread in the wilderness, as to fill so great a multitude?

ἐρημίᾳ erēmia “a secluded place”

And his disciples answered him, From whence can a man satisfy these men with bread here in the wilderness?

ἐρημίας; erēmias “this desolate place?”

In journeyings often, in perils of waters, in perils of robbers, in perils by mine own countrymen, in perils by the heathen, in perils in the city, in perils in the wilderness, in perils in the sea, in perils among false brethren;

ἐρημίᾳ, erēmia “[the] wilderness,”

(Of whom the world was not worthy:) they wandered in deserts, and in mountains, and in dens and caves of the earth.

ἐρημίαις erēmiais “deserts”
