It's especially odd since there are many statements in the Tanakh that seem more plausibly indicative of resurrection than the one Jesus chose, like
Isaiah 25:7-8
"And he will destroy on this mountain the shroud that is cast over all peoples, the covering that is spread over all nations; he will swallow up death forever."
Isaiah 26:19
"Your dead shall live; their corpses shall rise. Those who dwell in the dust will awake and shout for joy! For your dew is a radiant dew, and the earth will give birth to those long dead."
Daniel 12:2-3
"Many of those who sleep in the dust of the earth shall awake, some to everlasting life and some to shame and everlasting contempt. Those who are wise shall shine like the brightness of the sky, and those who lead the many to righteousness, like the stars forever and ever."
One explanation for Jesus' strange choice is that the Sadducees didn't accept anything but the Torah (as in Samaritanism) so Jesus was limited to arguing for resurrection from the Torah, but most of the evidence for that seems to be from the church fathers speculating about why Jesus gave them such a weird argument, and it isn't mentioned by the sources you would expect to mention it like Josephus.
According to one source a few centuries later (
https://www.sefaria.org/Midrash_Tanchuma%2C_Bereshit.5.3?lang=en), the Sadducees used Job 7:9 to defend their belief, "As the cloud fades and vanishes, so those who go down to Sheol do not come up." So maybe they accepted the whole Tanakh but gave some books like Job precedence over the prophets and defaulted to interpreting the prophets as speaking metaphorically wherever there were disagreements. But perhaps they gave the Torah the highest precedence and assumed literalism of all, so that was still what Jesus would've had to rely on to make the case for resurrection to them.
