Continuing on...
So, with the promises God made to Abraham having been fulfilled…
”a great nation”…speaking specifically about natural ethnic
Israel…
....
Sorry, but most of your post is a not in plain language that the non-college educated here can understand. Jesus said let your yeahs be yeah, and your nays be nay.
FACT: most brethren in Christ don't understand the difference in God's Word between the separate mention of Judah and Israel in the same sentence, like this...
1 Kings 16:29
29 And in the thirty and eighth year of Asa king of Judah began Ahab the son of Omri to reign over Israel: and Ahab the son of Omri reigned over Israel in Samaria twenty and two years.
KJV
Asa = "king of Judah", reigning at Jerusalem, as the house of David.
Ahab = king "over Israel", reigning over Israel at Samaria in the north.
Another example of many showing the 2 separate kingdoms then, the 'kingdom of Judah' and the 'kingdom of Israel'...
2 Kings 13:1
13 In the three and twentieth year of Joash the son of Ahaziah king of Judah Jehoahaz the son of Jehu began to reign over Israel in Samaria, and reigned seventeen years.
KJV
Joash = "king of Judah" (at Jerusalem)
Jehu = king "over Israel in Samaria". (Samaria was a city in the northern holy land)
Thus actual BIBLE SCRIPTURE reveals simply the existence of two 'separate' kingdoms involving the children of Israel after the split of old Israel per 1 Kings 11.
God said, through His prophet, to Jeroboam of the tribe of Ephraim...
1 Kings 11:30-31
30 And Ahijah caught the new garment that was on him, and rent it in twelve pieces:
31 And he said to Jeroboam, "Take thee ten pieces: for thus saith the LORD, the God of Israel, Behold, I will rend the kingdom out of the hand of Solomon, and will give ten tribes to thee:"
KJV
1 Kings 11:35-37
35 "But I will take the kingdom out of his son's hand, and will give it unto thee, even ten tribes.
36 And unto his son will I give one tribe, that David My servant may have a light alway before Me in Jerusalem, the city which I have chosen Me to put My name there.
37 And I will take thee, and thou shalt reign according to all that thy soul desireth, and shalt be king over Israel."
KJV
So let's see how you do with having to keep to the 'flow' of actual Bible Scripture line upon line...
1 Kings 12:19-24
19 So Israel rebelled against the house of David unto this day.
The "house of David" represents the king line from the tribe of Judah reigning at Jerusalem. At this time in history, Solomon's son Rehoboam was king over all Israel, but then God would change that, as He said He would rend the kingdom because of Solomon's pagan corruptions from his many wives.
20 And it came to pass, when all Israel heard that Jeroboam was come again, that they sent and called him unto the congregation, and made him king over all Israel: there was none that followed the house of David, but the tribe of Judah only.
Jeroboam was of the tribe of Ephraim, not Judah. Only the tribe of Judah was to be the king tribe, but God changed that since Solomon rebelled against Him (per 1 Kings 11).
Thus Jeroboam, of the tribe of Ephraim, became king over the "Israel", which starting at that time was put only... for the northern ten tribes he was given by God Himself.
But for Rehoboam, Solomon's son, of the house of David, at Jerusalem, he would remain king over the tribes of Judah, and the tribe of Benjamin with him, in Judea in the southern land. Eventually the tribe of Levi would be included. These are the JEWS of the "house of Judah" per God's Word, and per the Jewish historian Josephus.
This means at that time of the split, the name "Israel" applied specifically to the northern ten tribe "kingdom of Israel" which God gave Jeroboam to reign over.
"Judah" was used for those of the "kingdom of Judah" which Rehoboam, Solomon's son, reigned over at Jerusalem.
21 And when Rehoboam was come to Jerusalem, he assembled all the house of Judah, with the tribe of Benjamin, an hundred and fourscore thousand chosen men, which were warriors, to fight against the house of Israel, to bring the kingdom again to Rehoboam the son of Solomon.
22 But the word of God came unto Shemaiah the man of God, saying,
23 "Speak unto Rehoboam, the son of Solomon, king of Judah, and unto all the house of Judah and Benjamin, and to the remnant of the people, saying,
24 Thus saith the LORD, Ye shall not go up, nor fight against your brethren the children of Israel: return every man to his house; for this thing is from Me." They hearkened therefore to the word of the LORD, and returned to depart, according to the word of the LORD.
KJV
The "house of Judah" (Jews) mentioned separately, but in conjunction with the "house of Israel" (ten tribes)...
Jer 3:17-18
17 At that time they shall call Jerusalem the throne of the LORD; and all the nations shall be gathered unto it, to the name of the LORD, to Jerusalem: neither shall they walk any more after the imagination of their evil heart.
18 In those days the house of Judah shall walk with the house of Israel, and they shall come together out of the land of the north to the land that I have given for an inheritance unto your fathers.
KJV
Why is the "house of Judah" and the "house of Israel" shown as having been separate, but at that future time will walk together??
It's because
starting at 1 Kings 11, because of what Solomon did, God split old Israel into 2 separate kingdoms. And the name ISRAEL began to be applied ONLY to the northern ten tribe "house of Israel" (also as just 'Israel', or as 'Samaria' its capital city, or as 'Ephraim', its head tribe, or as 'Joseph' the father of Ephraim, or as the "kingdom of Israel".)
Because of idol worship by the northern "kingdom of Israel" of ten tribes, God scattered them all out of the holy land captive to Assyria and the cities of the Medes, never to return as a majority.
Only those of the "house of Judah" remained in the southern holy lands, at Judea. These are the Jews, that name taken from the tribe of Judah (per Josephus). Because the Jews of the "house of Judah" were the only children of Israel left in the holy land, and the ten tribes scattered and lost among the Gentiles beyond Euphrates, the "house of Judah" began to be known as Israel, even though the majority of Israelites had been removed by God's Hand.
Thus today, the Jews of the "house of Judah" still do not know what happened to the ten lost tribes of Israel which God scattered. Even many of their scholars deny the Biblical fact that in the future the ten tribes will return and be put back by God, like that Jeremiah 3:18 Scripture reveals. But other Jewish scholars do see the ten tribes returning at some point. I think God was very clear about the return of the ten tribes, particularly in the Ezekiel 37 chapter.
Therefore, TRUE Judah (Jews) need to remember that it's the false Jews (Canaanite crept in unawares) of the "synagogue of Satan" that try to distort these Biblical facts about the two separate houses of Israel; and especially their attempt to distort any idea of the ten tribes having been re-planted in new lands in order to receive The Gospel of Jesus Christ and become Christ's Church.
