They shall not hunger nor thirst; neither shall the heat nor sun strike them: for he that has mercy on them shall lead them, even by the springs of water shall he guide them.
All Commentaries on Isaiah 49:10 Go To Isaiah 49
Eusebius of Caesarea
AD 339
“The merciful One will encourage them, and he will lead them by springs of water.” For the springs of Israel and of salvation are plentiful. The springs of Israel are those of the Old Covenant, and the springs of salvation are those of the New.
