In this chapter, Matthew recounts three of Jesus’ agricultural parables: the parables of the sower (Matthew 13:1-23), the weeds (Matthew 13:24-30) and the mustard seed (Matthew 13:31-32).  Jesus was much misunderstood in His day, and still is now.  He was not a rabbi wanting to extend Jewishness to the world, nor was He a military revolutionary working to overthrow the Romans, nor was He simply a wise teacher and kind miracle-worker.  He had come to announce that He is the King of God’s kingdom, with authority to explain what His kingdom is like and to command everything and person to submi

The parable of the weeds (Matthew 13:24-30) is separated from its explanation by the parable of the mustard seed and the parable of the yeast (Matthew 13:31-35).  Why?  The same thing happened before the explanation of the parable of the sower (Matthew 13:1-23) - Jesus encouraged the disciples to come to Him privately to ask its meaning.  They needed a secluded space for Jesus' tutorial.
 

Real justice often seems in short supply.  The righteous seem to suffer while the wicked prosper (Psalm 73:2-12).  But it will not always be like that.  Injustice will stop when Jesus comes back because He will judge the world in righteousness (Acts 17:31).  The only messenger-role that the angels will have on that day is to call people away to judgement.  On Christ's orders, they will select all who have not trusted in His atoning sacrifice and throw them into the fire of God's wrath.
 

Farming, fishing, and finance were the major industries of Jesus' day; many of these were family businesses.  That is why almost all His parables are based on these themes.  At least four of the disciples were fishermen and everybody in the Galilee province was familiar with net-fishing which took place at night with weighted nets supported by floats, to produce a vertical mesh in which the fish were trapped.  However, not all the fish were good for eating; some were thrown away or burned.
