Not taking anything out of context.
As a matter of fact, you are persisting in that below. If it were not for the possibility that your statements might create confusion in the minds of those who may not be that familiar with Scripture, I would let this go. However I am going to address each point.
Mat 10:5 These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not:
Mat 10:6 But go rather to the lost sheep of the house of Israel.
Verse 6 makes it very clear that at this time, the apostles were to limit themselves to Israel,
which was in fact Judea (if you study their history). Samaria is already excluded at this time, and
it was in Samaria that a mixed remnant of the 10 lost tribes was resident (as well as in Assyria, which has no bearing on this). So to bring in the lost tribes into this scene is to do violence to Scripture. The Lord said, “Do not go into Samaria” (at this time), but you are saying the opposite – that He sent them to the lost tribes!
Ten Northern Tribes who separated themselves from the house of Israel as Benjamin and Judah are still with the house of Israel is where the Disciples were sent out to find these lost sheep that are scattered abroad even amongst the Gentiles.
Now you are equating the “lost sheep” of Israel with the “lost tribes” but if that were true,
then the Lord would have also sent the apostles into Samaria at this time. He did not, because He was sending the apostles to those of Judah and Benjamin who were resident in Judea.
Mat 15:24 But he answered and said, I am not sent but unto the
lost sheep of the house of Israel.
This statement simply reiterates and emphasizes the fact that at this point in history, the Lord and His apostles were
limiting their ministry to Israel. This was spoken when the Lord was on the borders of Tyre and Sidon (Gentile territory). At this stage, the Lord would not minister to the Gentiles, but would send His apostles to them after His resurrection.
John 10:16 And
other sheep I have, which are not of
this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
Here “this fold” is the sheep of Israel, and the “other sheep” are the Gentiles who would be reached after the resurrection and would become a part of the Body of Christ,
hence “one fold” (Jew and Gentile in one Body) and
one Shepherd. The Jews did not believe that Gentiles could also be within that fold, hence this statement.
Jer 50:19 And I will bring Israel again to his habitation, and he shall feed on Carmel and Bashan, and his soul shall be satisfied upon mount Ephraim and Gilead.
Jer 50:20 In those days, and in that time, saith the LORD, the iniquity of Israel shall be sought for, and there shall be none; and the sins of Judah, and they shall not be found: for I will pardon them whom I reserve.
Once again, you are taking Scripture out of context. Notice here that the sins of Israel (10 tribes) and Judah (2 tribes) are
completely eradicated from sight. Has this happened? Not at all. Modern Israel is in unbelief and Jews do not recognize Christ as Savior (which is the greatest sin of all). So when will this Scripture be fulfilled? In the future after God begins to deal with Israel as a nation, and ultimately Israel is redeemed and restored. This passage points to the Millenium, and beyond, not to the time when Christ was on earth, or even now which is the Church Age.
