In 2Sa 8 and 10, David's victories over the seven surrounding
kingdoms (Zobah, Philistia, Moab, Syria, Edom, Ammon, Amalek) secure his own
kingdom. In this they may be compared to the seven thunders of the Apocalypse --
in which Christ's kingdom subjugates the whole earth (Rev 10:3): (1) David first
cleared Zion of enemies; (2) then brought "ark" to Zion (in Last Days terms,
this may signify the glorified saints being established in Jerusalem); and (3)
finally, the seven campaigns extend and secure the kingdom.
