These verses clearly indicate and give literal support to the idea that God still cares for the land of Israel. These verses are describing God caring about the very land of Israel. The text mentions in verse 15 that kings of other nations will bow down to the coming king of Israel. Verse 16 then says that God Himself will rebuild Zion (land of Israel) and He will appear there. Verse 17 says God will not ignore the pleas of those who call out from that land.
Remember the psalmist was going through a lot of a pain at the moment. The solution for the psalmist is to remember the fact that even though he has a short time to live in this world, God rules forever and there is coming a day where He will "right the wrongs" of this world and rule from Israel.
Although on man’s timetable it may seem that all of these things are taking a long time, God is infinitely patient so that as many people as possible may come to Him for salvation.
All of this leads us back to the psalmist himself. He is suffering at the moment for some unstated reason. He sees his solution by seeing life from God’s perspective.We also must remember that whatever happens to us in our lives. God is still in charge; He still rules over the world, and He will still "right the wrongs" according to His timetable.
