The same day there came certain of the Pharisees, saying unto him, Get thee out, and depart hence: for Herod will kill thee. And he said unto them, Go ye, and tell that fox, Behold, I cast out devils, and I do cures to day and to morrow, and the third day I shall be perfected. Nevertheless I must walk to day, and to morrow, and the day following: for it cannot be that a prophet perish out of Jerusalem. O Jerusalem, Jerusalem, which killest the prophets, and stonest them that are sent unto thee; how often would I have gathered thy children together, as a hen doth gather her brood under her wings, and ye would not! Behold, your house is left unto you desolate: and verily I say unto you, Ye shall not see me, until the time come when ye shall say, Blessed is he that cometh in the name of the Lord.
And when he was come nigh, even now at the descent of the mount of Olives, the whole multitude of the disciples began to rejoice and praise God with a loud voice for all the mighty works that they had seen; Saying, Blessed be the King that cometh in the name of the Lord: peace in heaven, and glory in the highest. And some of the Pharisees from among the multitude said unto him, Master, rebuke thy disciples. And he answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out.
Come, and let us return unto the Lord:
for he hath torn, and he will heal us;
he hath smitten, and he will bind us up.
After two days will he revive us:
in the third day he will raise us up,
and we shall live in his sight.
Then shall we know, if we follow on to know the Lord:
his going forth is prepared as the morning;
and he shall come unto us as the rain,
as the latter and former rain unto the earth.
And the Lord spake unto Moses and unto Aaron, saying, This is the ordinance of the law which the Lord hath commanded, saying, Speak unto the children of Israel, that they bring thee a red heifer without spot, wherein is no blemish, and upon which never came yoke: And ye shall give her unto Eleazar the priest, that he may bring her forth without the camp, and one shall slay her before his face: And Eleazar the priest shall take of her blood with his finger, and sprinkle of her blood directly before the tabernacle of the congregation seven times: And one shall burn the heifer in his sight; her skin, and her flesh, and her blood, with her dung, shall he burn: And the priest shall take cedar wood, and hyssop, and scarlet, and cast it into the midst of the burning of the heifer. Then the priest shall wash his clothes, and he shall bathe his flesh in water, and afterward he shall come into the camp, and the priest shall be unclean until the even. And he that burneth her shall wash his clothes in water, and bathe his flesh in water, and shall be unclean until the even. And a man that is clean shall gather up the ashes of the heifer, and lay them up without the camp in a clean place, and it shall be kept for the congregation of the children of Israel for a water of separation: it is a purification for sin. And he that gathereth the ashes of the heifer shall wash his clothes, and be unclean until the even: and it shall be unto the children of Israel, and unto the stranger that sojourneth among them, for a statute for ever.
He that toucheth the dead body of any man shall be unclean seven days. He shall purify himself with it on the third day, and on the seventh day he shall be clean: but if he purify not himself the third day, then the seventh day he shall not be clean. Whosoever toucheth the dead body of any man that is dead, and purifieth not himself, defileth the tabernacle of the Lord; and that soul shall be cut off from Israel: because the water of separation was not sprinkled upon him, he shall be unclean; his uncleanness is yet upon him. This is the law, when a man dieth in a tent: all that come into the tent, and all that is in the tent, shall be unclean seven days. And every open vessel, which hath no covering bound upon it, is unclean. And whosoever toucheth one that is slain with a sword in the open fields, or a dead body, or a bone of a man, or a grave, shall be unclean seven days. And for an unclean person they shall take of the ashes of the burnt heifer of purification for sin, and running water shall be put thereto in a vessel: And a clean person shall take hyssop, and dip it in the water, and sprinkle it upon the tent, and upon all the vessels, and upon the persons that were there, and upon him that touched a bone, or one slain, or one dead, or a grave: And the clean person shall sprinkle upon the unclean on the third day, and on the seventh day: and on the seventh day he shall purify himself, and wash his clothes, and bathe himself in water, and shall be clean at even. But the man that shall be unclean, and shall not purify himself, that soul shall be cut off from among the congregation, because he hath defiled the sanctuary of the Lord: the water of separation hath not been sprinkled upon him; he is unclean. And it shall be a perpetual statute unto them, that he that sprinkleth the water of separation shall wash his clothes; and he that toucheth the water of separation shall be unclean until even. And whatsoever the unclean person toucheth shall be unclean; and the soul that toucheth it shall be unclean until even.
When taken in context and understood as originally written, it is hardly surprising that you have difficulty understanding the interpretation that Joshua 19 has put upon these texts. I think anyone who reads them in their original context would have some difficulty in seeing how they might apply to the end of a 2000 year 'dispensation', due in 10 years time.
