'Cause' in the Bible

Therefore, if food causes my brother to stumble, I will never eat meat again, so that I will not cause my brother to stumble.

If others share the right over you, do we not more? Nevertheless, we did not use this right, but we endure all things so that we will cause no hindrance to the gospel of Christ.

Now if Timothy comes, see that he is with you without cause to be afraid, for he is doing the Lord’s work, as I also am.
