"I disapprove of you because of a few things you have done" or "I am angry with you because of a few things you did." See how you translated a similar phrase in [Revelation 2:4](../02/04.md).
Something that leads people to sin is spoken of as a stone in the road that people stumble on. Alternate translation: "who showed Balak how to cause the people of Israel to sin" (See: [[rc://en/ta/man/translate/figs-metaphor]])
