1. I have spoken these things to you that no cause of michshol (stumbling, falling) may trip you up.
2. They will put you under the cherem ban in the shuls. A sha'ah (hour, time) is coming when everyone who kills you will suppose they are offering avodas kodesh to Hashem. [YESHAYAH 66:5]
3. And these things they will do because they did not have da'as of HaAv or of me.
