'Overscrupulous' in the Bible

Only be careful that this liberty of yours [this power to choose] does not somehow become a stumbling block [that is, a temptation to sin] to the weak [in conscience].

To the weak I became [as the] weak, to win the weak. I have become all things to all men, so that I may by all means [in any and every way] save some [by leading them to faith in Jesus Christ].
