Charles Spurgeon Commentary Isaiah 48:21

"And they thirsted not when he led them through the deserts; he caused the waters to flow out of the rock for them; he clave the rock also, and the waters gushed out." — Isaiah 48:21 (ASV)

And they thirsted not when he led them through the deserts:

Neither shall you thirst, O redeemed one, when you are in the desert!

He clave the rock also, and the waters gushed out.

And yet, to conclude the chapter, stands this remarkable sentence:

He caused the waters to flow out of the rock for them:

Most unlikely places will yield you help.
