After many days thou shalt be visited: in the latter years thou shalt come into the land that is brought back from the sword, and is gathered out of many people, against the mountains of Israel, which have been always waste: but it is brought forth out of the nations, and they shall dwell safely all of them.
After many days thou shalt be visited - in wrath, by God (Isaiah 29:6, "Thou shalt be visited of the Lord of hosts with thunder, and with earthquake, and great noise, with storm and tempest, and the flame of devouring fire"). Probably there is allusion to Isaiah 24:21-22, "The host of the high ones ... shall be gathered ... as prisoners ... in the pit ... and after many days shall they be visited." I therefore prefer the English version to Grotius' rendering, 'Thou shalt get the command' of the expedition. The "after many days" is defined by "in the latter years" - i:e., in the times just before the coming of Messiah-namely, under Antiochus before His first coming, under Antichrist before His second coming.
In the latter years thou shalt come into the land ... against the mountains of Israel, which have been always waste - i:e., waste during the long period of the captivity, the earnest of the much longer period of Judea's present desolation (to which the language "always waste" more fully applies).
The land that is brought back from the sword, and is gathered out of many people. This marks the impious atrocity of the act to assail God's people, who had only begun to recover from their protracted calamities.
But it is brought forth out of the nations, and they shall dwell safely all of them - rather, 'and they (the Israelites) were brought forth out of the nations, and they dwelt safely all of them' (Fairbairn). The English version means, 'Against Israel, which has been waste, but which (i:e., whose people) is now (at the time of the invasion) brought forth out of the nations where they were dispersed, and shall be found by the invader dwelling securely, so as to seem an easy prey to him.'
