Nothing malicious...sometimes a bit of pointed/barbed humour gets the point across, it's just another method of delivering the message.
In response to your challenge:
Zech:14
3Then the LORD will go forth and fight against those nations, as when He fights on a day of battle. 4In that day His feet will stand on the Mount of Olives, which is in front of Jerusalem on the east; and the Mount of Olives will be split in its middle from east to west by a very large valley, so that half of the mountain will move toward the north and the other half toward the south.
16Then it will come about that any who are left of all the nations that went against Jerusalem will go up from year to year to worship the King, the LORD of hosts, and to celebrate the Feast of Booths.
Here we see that at the return of the L-rd, not only is it to Israel that He returns, but it is from Jerusalem that He reigns, and every nation that is left will sent representatives yearly to celebrate the Feast of Booths (Succoth)
Amos talks of the restoration of Israel as a nation...something that many deride because they think it has to be initially established in righteousness, but my understanding is that G-ds program includes the physical restoration of the people back to their land, and then their spiritual restoration to Him through recognizing their Messiah.
YHWH specifically identifies Himself with Israel..they have not been cast aside as a nation, but restored, and it is within the nation that His plans for them as His people Israel will unfold.
Amos 9:
14Also I will restore the captivity of My people Israel,
And they will rebuild the ruined cities and live in them;
They will also plant vineyards and drink their wine,
And make gardens and eat their fruit.
15I will also plant them on their land,
And they will not again be rooted out from their land
Which I have given them,
Says the LORD your God.
Where does this leave the Church...we are beloved by G-d, we have been bought with a price (the blood of the Lamb), and the L-rd will come for His glorious Bride both Jews and Gentiles that know Jesus.
My contention is that as individuals that know the mercy, grace and love of G-d, even when we were afar off and in rebellion against Him...we should seek G-ds favour on His people Israel, pray for them, encourage them, stand with them and not repeat the mistakes of the past where we despised them, denegrated them and called them Christ-Killers.
The underlying sin of Replacement Theology is that it causes people who embrace it to dismiss Israel, and to skim over what the Bible says about Israel, and how G-d views His people Israel, even when they have been stubborn and rebellious, He has not cast them adrift forever and just as His mercy has reached out to us, so in these days His mercy is being extended to the children of Abraham, Isaac and Jacob.
Jer 31:
37Thus says the LORD,
If the heavens above can be measured
And the foundations of the earth searched out below,
Then I will also cast off all the offspring of Israel
For all that they have done, declares the LORD.
