59:19 When the enemy. These great promises will be literally fulfilled in the last days of the coming tribulation period. Note especially Revelation 12:15-17.

But then “the LORD…on our side” will put him to flight (the Hebrew word translated “lift up a standard” is translated “put…to flight” in Deuteronomy 32:30).
