In Revelation 7 Jesus puts his mark of protection on 144,000 Jews from the 12 tribes of Israel. This will protect them from the 5th trumpet that unleashes locusts that look like horses with human faces and female hair and crowns and breastplates of iron and tails with stingers like scorpions.
These monsters torture everyone except those 144,000 Jews that were protected by the seal. It is then revealed that these 144,000 are all Jewish incels, and they have been redeemed.
So why did Jesus decide to save these Jews, and not the goyim?
This is odd. Also odd is that the only time the goyim are especially mentioned in this book is in Revelation 11:1-2. These verses say that the goyim are not admitted in the temple of God with "its worshipers" (which are presumably all Jews). The goyim are left outside and treated differently.
This reminds me of Matthew 15:24-26, where Jesus refers to us goyim as dogs.
I think the goyim can still be saved (at least those who let themselves be killed in the name of Christ - it's unclear if other goyim will also be saved), but why does Jesus give special privileges for the Jews?
Back when America was founded, "American" was implicitly a white man, likely a literal descendant of the early settlers - but this changed over time to be anyone of any race who merely lives within the physical boundaries of the US. In the same way, Jew was originally a strict racial, tribal definition (i.e., a Judahite - of the tribe of Judah specifically).
After Israel split into two kingdoms, a Judahite became a racial Israelite dwelling in the kingdom of Judah (who might be descended from any of the twelve tribes). This is how you see Jew used in Esther etc. during/after the exile - not always the tribe of Judah,
but it was still implicitly racial.
By the New Testament era, Jew had shifted to be a vague religious/geographical label. We see this in how the Herods are called Jews despite being Edomites (who are not even descended from Jacob, let alone Judah).
As for Jesus calling the Jews Abraham's seed, this is true but I think you're confusing Abraham and Jacob a bit here. Strictly speaking, Israelites were literal blood descendants of the man Jacob specifically, not merely his grandfather Abraham - so as with the Herods, one could be a "Jew" (from Abraham) while not actually being an Israelite.
Abraham fathered Isaac and Ishmael - but Isaac was the heir of the promise, and Ishmael was rejected. The Arabs today have descent from Abraham, but not from Jacob.
Isaac fathered Esau (aka Edom) and Jacob (aka Israel) - but Jacob was chosen, and Esau was rejected. Like the Ishmaelites, Esau's descendants the Edomites have descent from Abraham, but not from Jacob.
Various secular histories cover times when groups known to have no descent from Jacob became "Jews" through religion or geography. Some had descent from Abraham, but that wasn't a requirement either.
The DNA study I linked to lines up with this - the Jews themselves have acknowledged at various points that they have some descent from Esau/Canaan/etc., making them "Jews" religiously (Judaism) and geographically (their ancestors lived in Canaan), but but not in the actual, literal sense of being blood descendants of the patriarch Jacob.
