"Now to further understand this thought, look with me to Psalm 105...Psalm 105 verse 8. And here we have a whole psalm speaking about God's covenant relationship to Israel. And just picking it up in verse 8, "He hath remembered His covenant forever...that is His promise made with Israel...the word which He commanded to a thousand generations which covenant He made with Abraham and His oath unto Isaac and confirmed the same unto Jacob for a law and to Israel for an everlasting covenant." So Abraham, Isaac, Jacob, all of those people had the covenant repeated, "Which covenant was made to the nation as an everlasting covenant, saying, Unto thee will I give the land of Canaan the lot of your inheritance. When they were but a few men in number, yea very few and sojourners in it, when they went from one nation to another, from one kingdom to another people, He permitted no man to do them wrong, yea He reproved kings for their sake saying, Touch not Mine anointed and do My prophets no harm."
Now what the psalmist is saying is that when God called out Israel and established a covenant with them, He built into that covenant protection against Israel's injury and ultimate harm so that they would not be wiped out, so that He could fulfill ultimately His promise to them. So Israel then is said to be the apple of His eye, is said to be His special anointed, "Touch not Mine anointed."
Let me draw you to another passage in Deuteronomy chapter 28. And this gives us even another insight into God's relationship to this nation Israel. And in the chapter we find God promising blessing for obedience. In verse 10 it says, "All people of the earth shall see that thou art called by the name of the Lord," the world will see that you belong to Him. Then verse 13, "And the Lord shall make thee the head and not the tail and thou shalt be above only and thou shalt not be beneath."
Now the point that he's making there is of all the nations, Israel is to be the head. Of all the nations, Israel is to be the unique recipient of divine blessing. So Israel then is the apple of God's eye. Israel is the anointed of God. Israel is by design the head of all nations in terms of special and unique blessing."
Using "touch not my anointed" out of context for one's own purposes is no better than Joel Osteen using every mention of the word "treasure" in Proverbs to teach his congregation that God wants them to be rich. We can only stand firmly on God's Word when we stand upon it in its entirety. If we merely stack up half-verses and half-truths, we will eventually teeter, wobble, topple, and fall.
