'Frail' in the Bible

Keep awake, and pray that you may not enter into temptation: the spirit is right willing, but the body is frail."

Be wakeful, all of you, and keep on praying, that you may not come into temptation: the spirit is right willing, but the body is frail."

For what was impossible to the Law--powerless as it was because it acted through frail humanity--God effected. Sending His own Son in a body like that of sinful human nature and as a sacrifice for sin, He pronounced sentence upon sin in human nature;

Moreover here frail mortal men receive tithes: there one receives them about whom there is evidence that he is alive.
