MATT.15  And, behold, a woman of Canaan came out of the same coasts, and cried unto him, saying, Have mercy on me, O Lord, thou Son of David; my daughter is grievously vexed with a devil. But he answered her not a word. And his disciples came and besought him, saying, Send her away; for she crieth after us. But he answered and said, I AM NOT SENT BUT UNTO THE LOST SHEEP of the house of Israel.
Jesus said "I am not sent but unto the lost sheep of the house of Israel"
JEREMIAH 50  IN THOSE DAYS, and in that time, saith the Lord, the children of Israel shall come, they and the children of Judah together, going and weeping: they shall go, and seek the Lord their God.  They shall ask the way to Zion with their faces thitherward, saying, Come, and let us join ourselves to the Lord in a perpetual covenant that shall not be forgotten.  MY PEOPLE HATH BEEN LOST SHEEP: their shepherds have caused them to go astray, they have turned them away on the mountains: THEY HAVE GONE FROM MOUNTAIN TO HILL, THEY HAVE FORGOTTEN THEIR RESTINGPLACE.
Lost sheep go from the mountain to the hill. Why? They forgot their resting place. The sabbath?
ISAIAH 2  And it shall come to pass IN THE LAST DAYS, that the mountain of THE LORD'S HOUSE SHALL BE ESTABLISHED IN THE TOP OF THE MOUNTAINS, AND SHALL BE EXALTED ABOVE THE HILLS; and all nations shall flow unto it.  And many people shall go and say, Come ye, and let us go up to the mountain of the Lord, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of zion shall go forth the law, and THE WORD OF THE LORD FROM JERUSALEM.
Look what happens in the last days. Its back to the mountain
