'Fall Away' in the Bible

then the priest shall charge the woman with an oath of cursing. And the priest shall say to the woman, Jehovah make you a curse and an oath among your people, when Jehovah makes your thigh to fall away and your belly to swell.

And this water that causes the curse shall go into your bowels to make your belly swell and your thigh fall away. And the woman shall say, Amen, amen.

And when he has made her drink the water, then it shall be, if she is defiled and has committed a trespass against her husband, the water that causes the curse shall enter into her and become bitter. And her belly shall swell, and her thigh shall fall away. And the woman shall be a curse among her people.

Those on the rock are the ones who, when they hear, receive the Word with joy. And these have no root, who for a while believe, and in time of temptation fall away.
