'Weak' in the Bible

But all believers do not recognize these facts. Some, from force of habit in relation to the idol, even now eat idol sacrifices as such, and their consciences, being but weak, are polluted.

But take care lest this liberty of yours should prove a hindrance to the progress of weak believers.

For if any one were to see you, who know the real truth of this matter, reclining at table in an idol's temple, would not his conscience (supposing him to be a weak believer)

Why, your knowledge becomes the ruin of the weak believer--your brother, for whom Christ died!

Moreover when you thus sin against the brethren and wound their weak consciences, you are, in reality, sinning against Christ.

To the weak I have become weak, so as to gain the weak. To all men I have become all things, in the hope that in every one of these ways I may save some.
