Isaiah 60:21
19 The sun will no longer supply light for you by day, nor will the moon’s brightness shine on you; the Lord will be your permanent source of light—the splendor of your God will shine upon you. 20 Your sun will no longer set; your moon will not disappear; the Lord will be your permanent source of light; your time of sorrow will be over. 21 All your people will be godly; they will possess the land permanently. I will plant them like a shoot; they will be the product of my labor, through whom I reveal my splendor. 22 The least of you will multiply into a thousand; the smallest of you will become a large nation. When the right time comes, I the Lord will quickly do this!”
Matthew 15:13
11 What defiles a person is not what goes into the mouth; it is what comes out of the mouth that defiles a person.” 12 Then the disciples came to him and said, “Do you know that when the Pharisees heard this saying they were offended?” 13 And he replied, “Every plant that my heavenly Father did not plant will be uprooted. 14 Leave them! They are blind guides. If someone who is blind leads another who is blind, both will fall into a pit.” 15 But Peter said to him, “Explain this parable to us.”
Notes and References
"... Matthew 15:12-14 ... These verses are peculiar to Matthew and reflect what took place after Jesus and his disciples had retired from the crowd and entered the house (compare Mark 7:17). The disciples' question shows that the Pharisees understood enough of Jesus' parable to take offense (verse 12). The disciples' request to have the parable explained (verse 15) does not reveal them as being more obtuse than the Pharisees but shows that, in common with most Jews at the time, they held the Pharisees in high regard and therefore wanted to be certain of exactly what Jesus had said that had offended them so badly. Therefore verses 12-14 are not out of place. Jesus must disillusion his disciples as to the reliability of the Pharisees and teachers of the law as spiritual guides, as well as explain the parable. This is not to say that these verses turn the entire section (verses 1-20) into a personal attack on the Pharisees rather than on their use of the law; for the chief point for which they are blamed relates to their misunderstanding of the law. Jesus uses two images. The first (verse 13) predicts the rooting up of any plant the heavenly Father has not planted. Israel often saw herself as a plant God had planted (Psalm 1:3; Isaiah 60:21; compare 1QS 8:5; CD 1:7; 1 Enoch 10:16; Psalms of Solomon 14:2), and the prophets turned the image against them (Isaiah 5:1-7) ..."
