'Stumbleth' in the Bible

yet hath he not root in himself, but endureth for a while; and when tribulation or persecution ariseth because of the word, straightway he stumbleth.

Jesus answered, Are there not twelve hours in the day? If any man walk in the day, he stumbleth not, because he seeth the light of this world.

But if a man walk in the night, he stumbleth, because there is no light in him.

It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.

For in many things we all stumble. If any stumbleth not in word, the same is a perfect man, able to bridle the whole body also.
