'Weak' in the Bible

But God chose what the world thinks foolish to shame the wise, and God chose what the world thinks weak to shame the strong.

We are fools for Christ, but you are wise in Christ! We are weak, but you are strong! You are distinguished, we are dishonored!

But this knowledge is not shared by all. And some, by being accustomed to idols in former times, eat this food as an idol sacrifice, and their conscience, because it is weak, is defiled.

But be careful that this liberty of yours does not become a hindrance to the weak.

For if someone weak sees you who possess knowledge dining in an idol's temple, will not his conscience be "strengthened" to eat food offered to idols?

So by your knowledge the weak brother or sister, for whom Christ died, is destroyed.

If you sin against your brothers or sisters in this way and wound their weak conscience, you sin against Christ.

To the weak I became weak in order to gain the weak. I have become all things to all people, so that by all means I may save some.

That is why many of you are weak and sick, and quite a few are dead.
