King James Version
Yet hath he not root in himself, but dureth for a while: for when tribulation or persecution ariseth because of the word, by and by he is offended.English Standard Version
yet he has no root in himself, but endures for a while, and when tribulation or persecution arises on account of the word, immediately he falls away.New International Version
But since he has no root, he lasts only a short time. When trouble or persecution comes because of the word, he quickly falls away.
