Matthew 23:29 says, Woe unto you, scribes and Pharisees, hypocrites! because ye build the tombs of the prophets, and garnish the sepulchres of the righteous,  Jesus is still talking about the attitude of the scribes and Pharisees.  He said they built and maintained tombs for the prophets, but this was just a symbolic act without any real following  of what the prophets taught.  Verse thirty states, And say, If we had been in the days of our fathers, we would not have been partakers with them in the blood of the prophets.  The scribes and Pharisees attempted to exclude themselves from the killing of the prophets.  They said that had they been alive when the prophets were killed that they would not have taken part in the killing.  We may attempt to exempt ourselves from responsibility for Jesus's death on the cross, blaming it on the people of that day, but until we accept the fact that we are just as responsible, we cannot be saved.  To claim otherwise would make us just as guilty of hypocrisy as the scribes and Pharisees.  Verse thirty-one says, Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets.  Jesus told the scribes and Pharisees that they were children of those who killed the prophets, and they were just as guilty of the same attitude.  We are not guilty of sin because of who our parents are, but we are just as guilty as they were without Christ as our Savior and Lord.  We are neither saved nor condemned by the actions of our parents, but we are all guilty of being responsible for the death of Jesus on the cross.  Verse thirty-two says, Fill ye up then the measure of your fathers.  I believe that Jesus was telling the scribes and Pharisees then and us today to accept responsibility for our actions.  It was not just the fathers of the scribes and Pharisees who were responsible for the death of the prophets, but it was all who had the same attitude even after the fact.  In verse thirty-three Jesus asks, Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?  We need to remember that this was some of the religious leaders who prided themselves on their righteousness that Jesus was talking to.  Unless we have accepted Jesus as Savior and Lord, then this applies to us as well.  Verse thirty-four declares, Wherefore, behold, I send unto you prophets, and wise men, and scribes: and some of them ye shall kill and crucify; and some of them shall ye scourge in your synagogues, and persecute them from city to city:  Jesus told the scribes and Pharisees that He was going to send to them prophets and wise men, and that they would scourge, kill and crucify them.  I believe this applies to the disciples and all believers who have been abused and killed for their faith since Jesus' death on the cross.  Verse thirty-five says, That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar.  The scribes and Pharisees wanted to pronounce themselves innocent of the mistreatment and deaths of the prophets of God, but Jesus pronounced them guilty of the blood shed by all righteous men.  I don't believe that Jesus is saying that they would be held responsible for the sins of their forefathers, but that had they lived then that they would have participated in the acts committed against the prophets.  We cannot profess to honor the prophets of old while persecuting the prophets of today.  Verse thirty-six states, Verily I say unto you, All these things shall come upon this generation.  I believe that Jesus was saying that judgment will come to each generation for their sins.  We cannot claim that we would have been innocent in times past when we are guilty today.  In verse thirty-seven Jesus laments saying, O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!  Jesus said that Jerusalem, the city of God, had continually mistreated and killed God's prophets, even as God had attempted to offer His protection to His people.  God has always stands ready to gather those that believe in Him under His protective wing, but we often allow self desires to keep us from Him.  Verse thirty-eight says, Behold, your house is left unto you desolate.  When we reject God's protection, we will indeed be left desolate.  Until we accept Jesus as our Savior and Lord, we cannot expect to build anything of lasting value.  Simply claiming to follow Christ without really believing in Him is not enough.  Verse thirty-nine declares, For I say unto you, Ye shall not see me henceforth, till ye shall say, Blessed is he that cometh in the name of the Lord.  I don't believe that Jesus was speaking of seeing Him physically, but was speaking of seeing Him spiritually for Who He really is.  Until we spiritually acknowledge Who Jesus is, it does us no good to acknowledge Him as a physical Man Who lived at one time.
