When Judas the Hammerer went to war against the Persians, he began to have success against them. The account in 1 Maccabees says of his military victories that
εὐοδώθη σωτηρία ἐν χειρὶ αὐτοῦ
salvation prospered in his hand (1 Maccabees 3:6)
So the idea that salvation could be a political or military matter was certainly attested in ancient Judaism. The ancient notion of salvation incorporates political and military success, but includes much more than those notions. It also encompassed ideas of healing, and of eternal life.
