11 For with astammering lips and another tongue He will speak to this people,
12 To whom He said, “This is the arest withwhich You may cause the weary to rest,” And, “This is the refreshing”; Yet they would not hear.
13 But the word of the Lord was to them, “Precept upon precept, precept upon precept, Line upon line, line upon line, Here a little, there a little,” That they might go and fall backward, and be broken And snared and caught.
14 Therefore hear the word of the Lord, you scornful men, Who rule this people who are in Jerusalem,
15 Because you have said, “We have made a covenant with death, And with Sheol we are in agreement. When the overflowing scourge passes through, It will not come to us, aFor we have made lies our refuge, And under falsehood we have hidden ourselves.”
A Cornerstone in Zion
16 Therefore thus says the Lord God: “Behold, I lay in Zion aa stone for a foundation, A tried stone, a precious cornerstone, a sure foundation; Whoever believes will not act hastily.
This is very similar to Jesus' explanation of parables. God says He scatters understanding on any given subject throughout the Bible, and our job is to put it all together and see the amazing truth that results. Therefore, parables cannot be interpreted alone; they rely on the revelation of the rest of Scripture.
Christ did not speak in parables to make the meaning clear to just any reader! From the very beginning, God has supervised the writing of the Bible so that it cannot be understood without outside help. Even prophets and righteous men of old did not understand, nor did the multitudes who heard the parables of Christ. According to Romans 11, the meaning is veiled from most of mankind until the day God offers them salvation. They are relegated to unbelief until a later time (i.e. the Millennium or Great White Throne Judgment), lest they rebel and must be destroyed.
