of course to do so, we have to assume that the words attributed to Jesus in the gospels are accurate. Most of the copied bits are in Matthew: 5:10-11 lifts from Bava Kamma 93a, 5:24 echoed Avot 5:14, 5:28 lifts right from Kallah, chapter 1, 5:32 takes from Gittin 90a...there are a bunch more including how 7:3-5 is actually from Archin 16b).
Here is Jesus (via Matthew) taking talmudic ideas and repeating them in his teachings. Seems like a pretty clear endorsement of what the talmud says.
All of that is Talmud, written hundreds of years after Jesus.
